The album sold more than 11 million copies, earned two Grammy nominations and landed Kid Rock a slot on the Woodstock 1999 festival. Since then, he has collaborated with the likes of Bob Seger, Metallica, Sheryl Crow and the Roots, and has been nominated for a Grammy in the Best Rock Album category and for an Academy of Country Music Award. His most recent album, 2010's "Born Free," featured appearances by country singers Martina McBride and Zac Brown and rapper T.I.Sugarland, the duo of Jennifer Nettles and Kristian Bush, has had five No. 1 country singles and has repeatedly won awards as best vocal duo from both the Country Music Association and the Academy of Country Music. Last year Sugarland contributed a version of Bob Dylan's "Tonight I'll Be Staying Here With You" to the tribute album "Chimes of Freedom."The Steve Miller Band, led by singer-guitarist Miller, broke through with its eighth album, 1973's "The Joker," whose title track was a No. 1 hit. The band followed with "Fly Like an Eagle" and "Book of Dreams," both multiplatinum sellers. After a long gap between albums, Miller has released two albums in the past two years: 2010's "Bingo" and last year's "Let Your Hair Down."The seven-piece Trombone Shorty & Orleans Avenue is led by Troy "Trombone Shorty" Andrews, whose professional career began at age 7 when he joined his brother James' jazz band. With Orleans Avenue, Andrews has added funk, r&b and hip-hop to his New Orleans base. His 2011 album "For True" features contributions from Kid Rock, Beck, Warren Haynes and Lenny Kravitz. The group sold out its December show at the Wheeler and has played at the Bonnaroo Festival in Tennessee, Hardly Strictly Bluegrass in San Francisco, and Fuji Rock in Japan.
