 Within a year the band had reunited, with original members Leslie West (guitar, vocals) and Felix Pappalardi (bass, vocals) joined by new members Bob Mann (guitar, keyboards) and Allan Schwartzberg (drums).The resulting Japanese tour – specifically, the August 30 performance at Koseinenkin Hall in Osaka – spawned the recordings for "Twin Peaks", the group's second consecutive live album.The album is the only Mountain release to feature Mann and Schwartzberg, both of whom left shortly after the tour.
