We're recycling some old favorites this week. First, David Bowie releases his 20th anniversary DVD/two-CD set of the Glass Spider Tour. If you didn't like the gig in '87, you can probably skip this one. But for fans, it's a must-have showcasing his Sydney and Montreal performances with such energy and grandiosity that only the Goblin King can bring. Up next, Oh No! Oh My! comes back with Between the Devil and the Sea. The Austin-based band and perennial blogger darling doesn't disappoint singing witty pop lyrics with a bit of jangly sting. Although the entire album is worth a download, we recommend "Obi Wan" if you're feeling cheap. Last, jack-of-all-trades Ethan Hawke teamed up with songwriter Jesse Harris to produce the soundtrack of his upcoming film Hottest State. Although the album isn't perfect all the way through, the depth of its guest list is enough to make you buy it: Willie Nelson, Bright Eyes, Emmylou Harris, Cat Power, the Black Keys, and more. Be sure to download Nelson's "Always Seem to Get Things Wrong," which ironically, he gets so right, and Bright Eyes's "Big Old House." Also out this week, Junior Senior's Hey Hey My My Yo Yo and Okkervil River's The Stage Names.

We cover nothing new this week. OK, so technically that's a half-truth -- the albums are original but the artists featured have been around for quite some time. Corey Harris starts us off with his new record Zion Crossroads. Fans that know him as a bluesman will be hard-pressed to discover that he's turned reggae, but his authenticity hasn't changed. If you're still unconvinced, download "Heathen Rage." Up next, the British band Placebo attempts greater fame with Extended Play 07. We can't figure out why they haven't taken a greater hold in the States having played alongside legends like David Bowie and Michael Stipe; maybe, it's their androgyny or their accents. Whatever the holdup, their new CD takes a tune from each record and tacks on three live tracks, making this a must-have for Placebo lovers. A real treat is the live version of "Pure Morning," a track they rarely play. Finally, Shivaree releases a new cover album packed with love songs from the sleaziest dudes in music today. Tainted Love: Mating Calls & Fight Songs features tunes from Rick James, Michael Jackson and Ike Turner, but the real beauty is Ambrosia Parsley's deadpan delivery. "Don’t Stop" by Michael Jackson and Motley Crew's "Looks That Kill" have never sounded this awkward. Also this week, new albums for Common and Korn.

This week, it's all about the single. Some of these tracks have seen a proper release, others are tucked away within a larger album, but all have one thing in common: They're worth the 99 cents at iTunes. First up, twee-voiced Metric frontwoman Emily Haines whose song "The Bank" actually name-checks Huey Lewis. James Lavell's UNKLE production collective returns a full decade after their breakthrough effort, Psyence Fiction which included cameos from DJ Shadow and Richard Ashcroft. This time around, Josh Homme provides vocals for the killer track, the funky stomper, "Safe in Mind." It takes a supreme talent to get Frank Sinatra to visibly perk up during one of his swing-a-ding duets -- and Keely Smith was just the talent to bring that out of Ol' Blue Eyes in the song, "How Are Ya' Fixed For Love," from 1958. If you're going to own one some from buzz-band Eastern Conference Champions, better make it "Nice Clean Shirt" -- everything else on their full-length sounds like it's trying too hard. And finally, a duet that sounds like it came straight out of 1994 -- the Manic Street Preachers and former Cardigans lead singer Nina Persson join forces on "Your Love Alone is Not Enough," showing what it would be like if the Cardigans rocked instead of popped. Also: "Preview," a new song from the Yeah, Yeah, Yeahs.

Mid-July marks a summer lull for music lovers. New releases have slowed and we're left with a handful of sophomore albums. First, British pop band The Editors leaves us wondering if they're the identical twins of Interpol. You can hardly tell the difference. But is that such a bad thing? You decide if the CD is a downer by downloading "Smokers Outside the Hospital Door" and "The Racing Rats." Another UK import, the Magic Numbers, debuts their U.S. release of Those the Brokes -- an album that's been such a hit overseas that we had to review it in our August issue. Grab your copy on newsstands now. Last, the Chemical Brothers have done what they do best: put out another album of hit-worthy singles in an incongruent sequence. Their full-length, We Are the Night, isn't worth 99 cents, but a few singles by Fatlip, Willy Mason, and the Klaxons are worth the cherry pick. Alison Sudol, Rooney, and Raul Malo are also reviewed this week.

You'd think the Tuesday before the Fourth of July would be a big day for the music industry, a time when record labels would dump new product on listeners eager to provide a soundtrack for outdoor grilling. Well, then you'd be wrong. This week is a notoriously slow one, with the only notable release coming from Southern rapper T.I. -- so this week's podcast is a mixed bag, looking back at a few releases covered last week and ahead to what's coming up next week. Up first? "Send You No Flowers" off the Bad Brains' comeback record, Build a Nation, which features the original lineup and was produced by Beastie Boy Adam Yauch. Bloggers are already buzzing about Vampire Weekend, an odd-ball blend of Paul Simon, world music and The Strokes. Hear what all the fuzz is about on "A Punk," off the band's download-only three-song EP. Also this week: A look at the charity-record Healing the Divide, featuring a duet between Tom Waits and the Kronos Quartet; Jonathan Richman's new instrumental music; and readers request another track from Kelly Willis' first album in five years.

Did you check out The New York Times's drug tell-all on Ryan Adams? He nearly checked out on us early, so we're giving his new album, Easy Tiger, double play time this week. And for good reason -- this is the focused singer-songwriter breakthrough that he's been trying to put out for the last three years. While his duet with Sheryl Crow is a bit overdone, the song "Oh My God, Whatever, Etc." is worth your buck on iTunes as is his Neil Young-esque "Goodnight Rose." Next, although repetitive, is the Automatic Automatic, who are simply "The Automatic" in Europe but duplicate their name in America. (Yeah, it didn't make sense to us either.) But we do understand their new single, "Raul"; British teens have already declared it a summer hit. The Beastie Boys are also back with a new album, Suco De Tangerina, an all-instrumental, no-rapping record that features hits straight out of Starsky and Hutch, like "The Cousin of Death." It's so funky, you won't even notice they're not rhyming. Last, be sure to check out the new single from Kelly Willis, "Don't Know Why."

This week, it's all about reinvention. Bon Jovi turns country with fiddles and steel pedals on Lost Highway. It's something of a mixed bag for the Jersey rocker -- his compilation with Big and Rich is unforgivable, he makes up for it by a duet with LeAnn Rimes called "Till We Ain't Strangers Anymore." Next, former members of The Beta Band reconnect to make The Aliens. Their debut CD Astronomy for Dogs cranks out eight five-minute plus songs of summery pop and garage rock, the most notable being "Setting Sun." Last, the ultimate identity crisis group Mooney Suzuki reemerges with Have Mercy, a mix of country, rock and psychadellica. Skip the album and download "Good Ole Alcohol." Also featured this week: The Fragile Army from Polyphonic Spree.
