Stone Temple Pilots (commonly referred to as "STP") is a Grammy Award-winning American rock band consisting of Scott Weiland (lead vocals), brothers Robert (bass guitar, vocals) and Dean DeLeo (guitar), and Eric Kretz (drums, percussion).The band found immediate success with the release of their debut album Core in 1992, which was certified 8x platinum. Despite high sales, the album received negative reviews from critics who thought of the band as "grunge rip-offs". Throughout their career, STP became one of the most popular rock bands of the 1990s, but were plagued with problems stemming from Weiland's drug addiction and run-ins with the law.
