In late 1964 Rothchild discovered Paul Butterfield and his band. A first attempt at recording them was shelved (though later released in the 1990s) but a later effort resulted in the band's self-titled debut release, "The Paul Butterfield Blues Band". Rothchild also produced the band's second album, "East-West", one of the most influential albums of the 1960s and the first example of what became acid rock. The early Butterfield Blues Band members were inducted into the Rock and Roll Hall of Fame in 2015.
