hit in Germany." California also wrote Spirit's other hit, "Nature's Way", for the band's best-selling album, Twelve Dreams of Dr. Sardonicus. Career Spirit was invited to open for Jimi Hendrix at Woodstock. However, band manager/producer Lou Adler—who had been one of the founders of the rock festival movement two years earlier, as a partner (with Mamas & Papas linchpin John Phillips) in the Monterey Pop Festival, where Hendrix premiered in the U.S.—opposed it because the band was busy promoting their latest album, Clear. When Ferguson and Andes left Spirit to form Jo Jo Gunne due to the slow sales of Sardonicus, and then his dear friend Hendrix died, a depressed California left Spirit. He recorded Kapt.
