Are both Stone Temple Pilots and Transvision Vamp considered American rock groups?
Stone Temple Pilots Stone Temple Pilots (sometimes abbreviated as STP) is an American rock band from San Diego, California, that originally consisted of Scott Weiland (lead vocals), brothers Dean (guitar) and Robert DeLeo (bass, backing vocals), and Eric Kretz (drums). From the band's formation in 1989, its line-up remained unchanged until the firing of Weiland in 2013, who was replaced by Linkin Park vocalist Chester Bennington. In 2015, Bennington left the band to focus solely on Linkin Park. On December 3, 2015, Weiland was found dead on his tour bus before a performance with his band The Wildabouts. In 2016, the band launched an online audition for a new lead vocalist.
Transplants (band) Transplants are an American punk rock/rap rock supergroup. They formed in 1999 when Tim Armstrong (of the bands Rancid and Operation Ivy) played his friend and roadie Rob Aston some beats he had made using Pro Tools and asked Aston if he would consider contributing lyrics. Initially, Armstrong played all the instruments himself but as the project grew, he invited musician friends such as Matt Freeman (Rancid), Lars Frederiksen (Rancid), and Vic Ruggiero (The Slackers) to add to the sound. Before long, Armstrong and Aston decided to officially form a band, but to make things complete, they wanted a drummer, so Travis Barker from Blink-182 was asked to join in 2002.
