We all show up at our rehearsal spot, and we're sitting around looking at each other," Alan remembers. No one brought any tunes. So we're like, 'What're we gonna do?'" The drummer laughs. Slowly we started working on some stuff. I threw something in, Eric threw something in, Neal threw something in. And it all ended up being vocal-based."

Vocals aren't entirely new for Soulive: Featuring appearances from soul-music luminaries like Chaka Khan, Ivan Neville and Corey Glover, Break Out found the trio beginning to push its music in a less improvised, more song-based direction. But this time the band-experienced collaborators who've recorded with Dave Matthews, Talib Kweli and Meshell Ndegeocello, among others-craved bigger change.

We've been playing instrumental music for eight years," Alan says, and we love doing it. But we've always strived to reinvent ourselves; none of us wants to hear the same old thing all the time." The drummer cites in particular his and his bandmates' varied solo and side projects (including Krasno's production work with the Fyre Dept.) as having fueled their desire for a makeover. So for the first time, Soulive increased its ranks, inviting singer Toussaint-a versatile Boston-based vocalist who's spent the past several years touring the East Coast with his reggae outfit the China Band-to join the group on a permanent basis. After nearly a decade as a trio, Soulive is now a quartet.

This isn't the three of us featuring a guest singer," Alan says. It feels like it's a new band. All of us wanted to go in a different direction; outside of Soulive, we were all doing more song-based stuff. So we just figured, Why don't we go in that direction inside the band? It's just music. We don't wanna get caught up in what genre or style it is. If we wanna get up there and play death-metal polka, it'll still be Soulive playing it."

For better or for worse, No Place Like Soul, Soulive's sixth studio full-length, contains no death-metal polka. What it does feature is the band's sharpest, most mature songwriting to date, with thoughtful nods to funk, soul, rock, hip-hop, reggae and old-school R&B. Waterfall" kicks the album off in fine style, Toussaint expressing his need to wash my mind clean" while his new bandmates chew up a deep Memphis-soul riff. In Comfort" a head-nodding beat stirs in the flavor of the street, and in Bubble" Alan pays tribute to Led Zeppelin's John Bonham. Outrage," one of the disc's two instrumental tracks, charges along on Krasno's fleet-fingered guitar work, while Mary" slows things down a bit; it's a laidback acoustic soul tune that should soundtrack backyard barbecues all summer long. Throughout the expansive, wide-ranging 13-track disc, Soulive navigate this new sonic terrain with the expert abilities they've honed by logging countless hours on stages across the world. Guys who know what they're doing but retain an appetite for the unknown, they've managed to produce that rarest of musical accomplishments: a record that sounds classic and forward-thinking at the same time.

The quartet spent the latter half of 2006 recording No Place Like Soul with producer Stewart Lerman, who's also worked with such disparate talents as Loudon Wainwright III, Dar Williams and Vinicius Cantuaria. Alan explains that when the band first set up shop in Lerman's Greenwich Village studio, the Shinebox, the plan was to write and demo at the same time, then take the best material to a different studio to track the album. But everyone ended up happy with what they laid down at the Shinebox. Alan says he and the band dug the personality and the spontaneity they captured in Lerman's space and didn't want to risk sacrificing those qualities by rerecording the music elsewhere.

It's a mindframe that demonstrates the perfect fit between Soulive and the relaunched Stax. I'm so excited," the drummer says of the band's affiliation with the label. When I get the final version of the album with the Stax logo on it and everything, that'll be a huge accomplishment for me. Back in the day, everyone on Stax had their own thing: Isaac Hayes, Otis Redding, the Bar-Kays, Carla Thomas-they were real individuals. There's character in that music, and we're ecstatic to be doing our thing as a part of that lineage."
