The album was originally released in Europe and America in 1971 with different cover artwork. The 1973 US reissue featured a third version of the cover artwork. In 1983 the album was re-released on LP in Germany and four years later also for the first time on CD. The digital remastered version of the album premiered on CD in 2008.

After the 1969 classical / rock fusion Concerto for Group and Orchestra, Jon Lord was commissioned to write a follow-up. This was Gemini Suite, five long movements inspired by the members of Deep Purple, and performed live in September 1970 at the Royal Festival Hall with The Light Music Society Orchestra (the album of the concert was issued in 1993 as Gemini Suite Live). Jon Lord then recorded it in the studio as his first solo project in 1971, with the London Symphony Orchestra conducted by Malcolm Arnold and soloists drawn from the rock world. Gemini Suite was an important step for Lord and led to albums such as Windows (1974) and Sarabande (1976).

Recorded at Royal Albert Hall on April 4, 2014, the various editions combine to include the full evening’s program of nearly three hours of music featuring Deep Purple, Bruce Dickinson, Glenn Hughes, Miller Anderson, Rick Wakeman, Micky Moody, Bernie Marsden, Neil Murray, Steve Balsamo, Phil Campbell, Jeremy Irons and more.

A concert held in the memory of ex-Deep Purple keyboardist Jon Lord, featuring performances from an assortment of his friends and bandmates.

Windows is a live album by Jon Lord and the German conductor and composer Eberhard Schoener; the music and the record are primarily credited to Lord. It was taped at a concert in Munich, (West) Germany on 1 June 1974 and the music is a mix between progressive rock and orchestral late romantic/modernist styles.

Джон Лорд - выдающийся английский композитор и клавишник, наиболее известен участием в группе Deep Purple. Concerto for Group and Orchestra - знаменитые хиты Deep Purple в симфо-роковых аранжировках. Студийная запись этого концерта была для него давней мечтой. Альбом стал своего рода завещанием великого музыканта, ушедшего из жизни 6 июля 2012 года.
