Elvis Costello will release a 7-inch single on Record Store Day featuring a cover of Squeeze’s “Someone Else’s Heart” — off 1981’s East Side Story, which he co-produced — that was recorded in 2011 with members and associates of hip-hop collective The Roots. Full details right here.

For the past few days, Elvis Costello’s Twitter account has been teasing some sort of mystery release that’s due out on the Fourth of July, initially available in a now-sold-out 10-inch 45 rpm single, but which also will be available digitally starting tomorrow. Not much else is yet known about the release.

We posted some audience video out of the one-off Elvis Costello and The Roots show in Brooklyn last week, but now comes something far better: Pro-shot footage from the Roots-affiliated okayplayer of Costello, ?uestlove and Co. playing a sizzling, 13-minute version of Costello’s Blood & Chocolate classic “I Want You.”

Elvis Costello and The Roots have been busy this week promoting their just-released new album Wise Up Ghost, performing in Brooklyn Monday night — where they covered The Specials’ classic “Ghost Town” — and appearing on “Late Night With Jimmy Fallon,” aka ?uestlove and Co.’s day job, on Monday night.

This week’s new releases include brand-new studio albums from The Mission, Elvis Costello and The Roots, Sebadoh and Berlin, plus a live DVD/Blu-ray release from Peter Gabriel, a 1992 live album from The Wedding Present and an audiophile vinyl pressing of The Sisters of Mercy’s ‘Floodland.’

As advertised, Peter Hook was featured on Thursday night’s episode of “Late Night with Jimmy Fallon,” where he sat in with The Roots, playing Joy Division and New Order classics — with Captain Kirk Douglas handling vocals — as the show went to and from commercial.

Peter Hook’s North American tour gets underway tonight in Boston — he’ll be performing New Order’s first two albums, 1981′s Movement and 1983′s Power, Corruptions & Lies, in their entirety each night — and the bassist is using the occasion to drop by “Late Night with Jimmy Fallon” when the trek hits New York.

The unlikely pairing of Elvis Costello and The Roots this week debuted the first fruit of their new collaboration, premiering on Pitchfork the single and lyric video for “Walk Us Uptown,” the first single off the forthcoming Wise Up Ghost. The album is due out Sept. 17 on Blue Note Records.

Elvis Costello has traded The Imposters for The Roots, teaming up with the venerable hip-hop act and “Late Night with Jimmy Fallon” house band to record a brand- new full-length album called Wise Up Ghost that will be released by Blue Note Records this September.

The Jesus and Mary Chain’s brief run through Texas last month appears to be the beginning of an active 2012: In addition to today’s announcement of the band’s first-ever concert in China, the brothers Reid also will come back to the U.S. for a string of new dates in both June and September.

It’s Bruce Springsteen week over at “Late Night with Jimmy Fallon,” and last night saw Elvis Costello stop by the show to help celebrate the release of the Boss’ new album. Backed by The Roots, Costello played Springsteen’s “Brilliant Disguise” on air and stuck around for a web-only performance of “Fire.”

Sure, it was no Sugar reunion, but it was nice to see Bob Mould and The Roots jam through ‘Copper Blue’ stand-out ‘If I Can’t Change Your Mind’ on last night’s ‘Late Night with Jimmy Fallon’ — even if it was only a minute long.

Sonic Youth’s Thurston Moore dropped by ‘Late Night with Jimmy Fallon’ last night to play a couple songs off his new solo album ‘Demolished Thoughts.’ Check out ‘Circulation’ and the web-only ‘Blood Never Lies.’
