In 1970, the American rock band Santana released Abraxas, its second studio album. Its cover featured a psychedelic interpretation by German-French painter Mati Klarwein of the Annunciation scene in which Mary is informed by the archangel Gabriel that she will be the mother of the son of God. Perhaps playing with this idea, designer Günther Kieser nails a different psychedelic winged figure (a butterfly) to a blank wall (possibly alluding to the crucifixion of Christ) in his announcement for the West German tour for that album. Some music historians have suggested that Kieser is representing the balance between beauty and evil, a nod to the band’s 1969 song “Evil Ways.” Interestingly, a butterfly appeared on the cover of Santana’s sixth album, Borboletta (the Portuguese word for butterfly), in 1974. After a breakout performance at Woodstock in 1969, Santana achieved global popularity, with its first album debuting a few weeks later at number four on the American charts. The band’s second album (the related concert for which is advertised by this poster) debuted at number one in the United States and at number four in Germany. Folk singer and songwriter Karen Dalton opened for Santana during its European tour; however, she found the intensity and size of the crowds for the headlining band overwhelming, an experience that ultimately led to her early retirement from the spotlight.
