The Southern hip-hop duo called Rehab were literally a product of their namesake. Original members Danny Boone and Brooks Buford, both recovering alcoholics and drug addicts, met at a local rehab facility and connected over their love of music. Mashing rap with rock, the duo released their debut album, Southern Discomfort, in 2000 on the Sony label. Cee-Lo, Goodie Mob, and Cody ChesnuTT were some of the guests on the album, which would spawn the Top 15 modern rock hit "It Don't Matter." Two years were spent on the road supporting the album, including a stint on the Vans Warped Tour, and then the duo splintered. Boone retained the name and recruited four veteran musicians for a new Rehab. Now a quintet with Boone as the lone singer/rapper -- and also using his birthname, Danny Alexander -- Rehab signed with Arshid Entertainment and released the ambitious Graffiti the World in 2005.
