The Jimi Hendrix Experience released their third UK single, "The Wind Cries Mary" backed with "Highway Chile" May 5, 1967 on Track Records (604 004). The song was originally recorded at DeLane Lea Studios in London on February 3, 1967, and became a popular hit, released as a single and then later as part of the US version of the first Jimi Hendrix Experience album, 'Are You Experienced?' Polydor Records was the international distributor.

This pre-release tape from Ryemuse Sound Studios in London, is a 1/4" tape on 7" reel, at 15 IPS (speed), MONO recording, a typical format used professionally at that time. A studio executive or audio engineer at Polydor Records received this copy, made directly off of the master recording from Track Records. Polydor had this single manufactured and released (mainly in Europe) in the summer of 1967.

Audio engineer George Marino (Sterling Sound) and John McDermott (Jimi Hendrix Estate) reviewed this tape circa 2001, determining it was a discreet mono mix (as released), and was authentic. The tape is in its original box, and is in undamaged clean condition.
