In the early '70s, Santana helped out another Bay-area band that went on to a five-decade career: Tower Of Power. Carlos Santana enlisted them as an opening act when ToP's first album came out.
"We were hot in the Bay area, but in the rest of the country we were nothing," Tower Of Power founder Emilio Castillo told Songfacts
. "But Carlos was into the band. And mind you, every night, we gave him a run for his money. A lot of guys would have just said, 'I ain't going to have those guys open for me, I look bad.' But I believe he felt it made him play better and urged him on. So he took us all over the country and people had no idea who we were."
