1986: Mighty Joe Young Formed
According to a 1993 SPIN article, Scott Weiland had been playing in bands since he was 15 and met bassist Robert DeLeo at a Black Flag concert in Long Beach. After recruiting DeLeo's brother Dean on guitar and Eric Kretz on drums, the group recorded a demo as Mighty Joe Young. The name, however, already belonged to a blues musician, so the band chose Shirley Temple's Pussy as an alternative. After signing with Atlantic Records in 1989, the band was pressured to rename again, settling on Stone Temple Pilots to maintain the STP initials.
