The Open Mind were a London-based psychedelic rock band active in the 1960s and 1970s. The band was formed in the mid 1960s by four musicians from Putney, South London. Initially named The Apaches formed by Tim du Feu, Mike Brancaccio and Philip Fox and their friend Ray Nye. Nye left in 1965 and another friend joined instead Terry Schindler. The band became The Drag Set, who released a little-known single in February 1967, "Day and Night" / "Get Out of My Way". Shortly thereafter, they changed their name to The Open Mind and in July 1969 released a self-titled LP which has since become a highly sought-after collectible. The band, however, is best known for its druggy August 1969 single, "Magic Potion" (which also marked the introduction of double-bass drums in rock music), which did not appear on the album.
The Open Mind disbanded in 1973; its members wanted to move into jazz-influenced music, but The Open Mind was too well-known as a psychedelic band. The band members (minus Phil Fox) went on to form Armada, which lasted about three years but did not release any recorded material.
Despite their paucity of recorded material, The Open Mind have proven to be influential in the psychedelic rock genre. The noted 1990s psych group Sun Dial paid tribute to the band with a cover of "Magic Potion" on their 1993 album Return Journey.
