Klarwein's painting Annunciation (1961) was seen in reproduction by the musician Carlos Santana, who subsequently used it as the cover image of his band Santana's second album Abraxas (1970). In the following years Klarwein produced comparably striking designs for the covers of two Miles Davis albums, Bitches Brew (1969) and Live-Evil (1971), as well as a portrait of Jimi Hendrix, which was supposed to have been used for the guitarist's collaboration album with big band leader Gil Evans, which never came to fruition due to the guitarist's death.
