More Keys Please: Devout Alicia Keys fans will want to nab the CD+DVD version of Unplugged, which boasts two additional audio performances, "Goodbye" and "Butterflyz," on the CD, and behind-the-scenes action and a video for "Unbreakable" on the DVD. That's not to mention a booklet that has poems, a letter from Keys, liner notes, photos and info on Keep a Child Alive, a nonprofit she aligned herself with for a World AIDS Day benefit last year.

Leading a Double Life: DualDiscs are all the rage, and record companies usually send them to stores at the same time as the standard album in order to maximize sales potential. Not so with Ricky Martin's Life, which will come out in regular form Tuesday but won't see a DualDisc release until November 22. Tracks on both editions include: "I Don't Care" (featuring Fat Joe and Amerie), a Luny Tunes reggaeton remix of "Que Mas Da" and the Spanish track "Déjate Llevar (It's Alright)."

A New G Thang: G-Funk guru Warren G resurfaces after his longest solo hiatus yet -- nearly four years -- with the indie release In the Mid-Nite Hour. After spending time with 213 for last year's The Hard Way, Warren gets some help from his comrades on a few tracks: Snoop crops up on "Chronic Break" and "Garilla Pimpin," while Nate Dogg chimes in on "We Need Each Other." Raphael Saadiq, Bishop Lamont and Chuck Taylor also lend their skills.

Dive Right In: Originally called [Adult Swim] Presents DangerDoom, The Mouse and the Mask still realizes what Danger Mouse and MF Doom set out to do: high-five the animated-TV block with a set of inspired songs, plus character voices and skits from shows like "Aqua Teen Hunger Force" and "Sealab 2021." Cee-Lo and Ghostface Killah dip their toes into "Benzie Box" and "The Mask," respectively.

United They Stand: In addition to this week's two metal-champ collections -- Numbers From the Beast: An All-Star Tribute to Iron Maiden and the Roadrunner Records 25th anniversary throwdown The All-Star Sessions -- there's a spate of other kinetic alliances happening. Illinois punks Resident Genius jam along to a recorded phone conversation they shared with legendary Boston University prof/activist Howard Zinn for You Can't Blow Up a Special Relationship; elusive indie darling Chan Marshall (a.k.a. Cat Power) hops onto grimy Aussie instrumental trio Dirty Three's Cinder; and ex-Swans singer Jarboe duets with members of Low, Ministry and Bauhaus on her new one, The Men Album. (For three points: Blixa Bargeld of Nick Cave & the Bad Seeds also sings with Jarboe; her fellow Seed, Warren Ellis, is Dirty Three's violinist.)

SteEPed in EPs: Neo-goth dance punks American Eyes find an unlikely producer in Michael Patterson (Diddy, Notorious B.I.G.) for their first release, Never Trust Anything That Bleeds; likewise, chaotic London punks the Rakes make their debut with Retreat. Also, Lambchop pay Nashville neighbors Hands Off Cuba a visit with Colab; the country-rockin' Magnolia Electric Co. taped two of their Hard to Love a Man tracks at Steve Albini's, uh, Electrical Audio Studios; San Francisco solo artist Kelley Stoltz breaks bread with Sub Pop on The Sun Comes Through; and another solo artist, Amanda Rogers, goes even further out on a limb by covering At the Drive-In, among others, on Something Borrowed Something Blue.

Song Title of the Week: "Major Disappointment Reporting for Duty" (Drowningman's Don't Push Us When We're Hot)

Other Notables:

Sevendust's Next: After eight years and a bitter breakup with career-long label TVT Records, the metal squad is resurrecting itself with a fresh new label (the Universal-affiliated WineDark), single ("Ugly") and guitarist, Snot's Sonny Mayo. Keep an eye out for limited-edition copies of 'Dust's fifth studio record, which come with a bonus DVD.

Gang of Four's Return the Gift: The truly seminal U.K. dance-rock group initially decided to put out a batch of re-recordings of its classic songs as a stand-alone disc and hold off until 2006 for an equally tempting set of remixes by Hot Hot Heat, Yeah Yeah Yeahs, No Doubt's Tony Kanal and others. Now they've decided to simplify by melding the two into a 26-track, double-CD set.

Modest Mouse's Good News for People Who Love Bad News DualDisc: Humble-rodent connoisseurs probably have the bonus track "I've Got It All (Most)" -- which previously appeared as a B-side but is tacked onto the Good News DualDisc for good measure -- but they should take note of the many visual nuggets: two videos, behind-the-scenes stuff and an interview with main man Isaac Brock directed by -- you guessed it -- Isaac Brock.
