Since he had joined Santana in 1972, keyboard player Tom Coster had been Carlos Santana's right-hand man, playing, co-writing, co-producing, and generally taking the place of founding member Greg Rolie.
But Coster left the band in the spring of 1978, to be replaced by keyboardist/guitarist Chris Solberg and keyboardist Chris Rhyme.
Despite the change, the band soldiered on, and with Inner Secrets, they scored three chart singles: the disco-ish "One Chain (Don't Make No Prison)" (#59), "Stormy" (#32), and a cover of Buddy Holly's "Well All Right" (#69), done in the Blind Faith arrangement.
(There seems to be a Steve Winwood fixation here.
The album also featured a cover of Traffic's "Dealer.") The singles kept the album on the charts longer than any Santana LP since 1971, but it was still a minor disappointment after Moonflower, and in retrospect seems like one of the band's more compromised efforts.
