Guru, Chuck D. Help Dirty Dozen Brass Band Reinterpret 'What's Going On'

Rappers Guru and Chuck D. are featured on The Dirty Dozen's upcoming album What's Going On, a reinterpretation of Marvin Gaye's classic 1971 album.

For almost 30 years, The Dirty Dozen Brass Band has taken the traditional brass band music of New Orleans and combined it with funk, jazz, gospel, soul and now rap.

The group has previously collaborated with such legends as Dizzy Gillespie, Elvis Costello, Dave Matthews, Widespread Panic and others.

The Dirty Dozen Brass Band and their label, Shout! Factory will donate a portion of the proceeds to Tipitina's Foundation, which benefits the music community of New Orleans.

The group decided to release the benefit album, after Hurricane Katrina destroyed the homes of founding members Roger Lewis, Kevin Harris and Gregory Davis homes.

Other guests featured on What's Going On include Ivan Neville, G. Love, Bettye LaVette and others.

What's Going On hits stores August 29th on Shout! Factory.
