The Red Hot Chili Peppers were formed in 1983 in California by Anthony Kiedis and Michael "Flea" Balzary. They struggled early on with drug addiction and commercial failure of their first album. Personnel changes occurred over the years including the death of original guitarist Hillel Slovak from a heroin overdose. Their 1991 album "Blood Sugar Sex Magik" featuring hits like "Under the Bridge" was a breakthrough success. The band has had enduring popularity releasing 10 albums to date and winning 7 Grammys, though individual members have left and rejoined the group at various points in their career.
