Apparently, I was more familiar with Jorge Strunz than I thought. It turns out he was one of the founders of the Latin jazz band Caldera.
'Caldera combined jazz, funk and rock with a wide variety of Latin music, influenced by 1970s fusion explorers like Return to Forever and Weather Report.
The four albums Caldera released did not sell (well), and the band called it quits in 1979 (though three out of their four albums have been reissued on CD and digital except for their third album Time & Chance).'
Of the four albums: Caldera (1976), Sky Islands (1977), Time and Chance (1978) and Dreamer (1979), I have three in my lp collection. Here is a wiki synopsis of Caldera's biography.
