Little Feat has done it again.

Some 40 years after the late Lowell George of Frank Zappa's Mothers of Invention teamed with keyboard player Bill Payne and started the band that shifts and swirls from rock to jam to blues to other formats, it has released a critically acclaimed album. This time out "Rooster Rag," takes the group deep into jazz.

"... We can play any kind of music that we want as long as we do it well. That was why the band was always so diverse and deemed eclectic by all the mediums when we first started," guitarist Paul Barrere, who joined the band in 1972, told Megan Lohre of Times soon after the album's release. "On one record you'd have a straight blues, a rhythm and blues, a rock and roll song, you could have a country song. It was always just kind of this diverse approach."

When jam band collaboration was still in its infancy, Little Feat was fine-tuning the art and gathering a die-hard fan base that included such luminary performers as Jimmy Buffett, Dave Matthews, Bob Seger and Vince Gill. Indeed, it was Buffett who teamed with Little Feat to release the 2008 project "Join the Band" that included major Little Feat songs played by the group and a high profile musical guests including Emmylou Harris, Bela Fleck, Bob Seger and others.

Barrere admits that after 40 years on the road, it's easy to grow weary of travel. Yet the six-member band is still deemed one of the hardest working bands in contemporary music.

"The best part about being on tour is the time that we spend on stage. At this point having traveled around for 40 some odd years is not as exciting as it used to be. Sleeping in different hotels every night, on buses, doesn't have the same allure it did when I was in my 20s and 30s," he said. "The playing, that's the payoff. I think most individuals have the same joke and it's that we do the gigs for free and get paid for traveling."
