According to Wiki,
Trombone Shorty (Troy Andrews) grew up in New Orleans' Tremé neighborhood and participated in brass band parades as a child, becoming a bandleader by the age of six. In 2005, Andrews was a featured member of Lenny Kravitz's horn section in a world tour that shared billing with acts including Aerosmith...As of 2009, his current project is Orleans Avenue, a funk/pop/hip-hop mix including musicians Mike Ballard on bass, Dan Oestreicher on baritone sax, Tim McFatter on tenor sax, Pete Murano on guitar, Joey Peebles on drums, and Dwayne "Big D" Williams on percussion.
He appeared in four episodes of the 2010 HBO series Treme.
Trombone Shorty's music combines classic jazz with more modern funk and hip hop. This makes him popular with younger fans, but leaves some fans of the classic titans of the genre shaking their heads. While I like BB King and and the other greats, I have never fully immersed myself in their world enough to speak critically on what is and is not jazz (or blues). I can speak to what I like, though, and Trombone Shorty falls into that category. I especially like his 2010 album Backatown.
