Originally composed of six Samoan-descended brothers from Los Angeles, the Boo-Yaa T.R.I.B.E. offered a distinctly authentic brand of gangsta rap. Following the 1988 single "Coming Hard to America" and a guest appearance on Club Nouveau's "No Friend of Mine," they released their debut album, New Funky Nation, in 1990. Earning positive attention for its use of live instrumentation, it spawned a minor hit single in "Psyko Funk," and climbed into the Top 40 of the R&B album chart. The group tried their hand at rap-metal on 1997's Angry Samoans, albeit to little attention, but managed to land on the R&B/hip-hop chart with 2003's West Koasta Nostra by snagging a rare guest appearance from Eminem. The all-metal affair Business as Usual, their eighth and final album, came out in 2006.
