"Taurus" is a rock instrumental by rock band Spirit, originally released on their self-titled debut album in 1968. The track, composed by guitarist/singer Randy California, was recorded in November 1967. It has been suggested that Jimmy Page borrowed the descending guitar figure from "Taurus" for Led Zeppelin's signature tune "Stairway to Heaven". Zeppelin opened for Spirit in an early American tour, leaving little doubt that Led Zeppelin had heard the Spirit song before Stairway to Heaven was written. I'm not familiar with this band at all.
