Zoetrope is a technology that is rather complicated to explain verbally; here is a video example.
The first two albums of this series of reissues are "Wonderwall Music", released in November 1968, and "Electronic Sound", released in 1969.
Released on November 1, 1968, “Wonderwall Music” was not only Apple's first official record release, but also the first album by a Beatle without the other three. The album represented for Harrison the possibility of amalgamating in music the two musical cultures, the Western and the Eastern, whose synthesis he had been a driving force since he discovered Indian music in 1965 through the sitar master Ravi Shankar.
Having received the commission from director Joe Massot, Harrison composed this soundtrack including Indian music and rock style songs, with experimental, psychedelic and atmospheric music.
The recordings were long and took place at separate times and studios, producing a total of thirty-six pieces, nineteen of which were included on the album. The sessions began with two days of recording (22-23 November 1967) at Abbey Road, where Harrison recorded some Indian-style numbers, of which apparently only one (the fragment incorporated into “Dream Scene”) would be included on the album: “India” (or “Fool's Dance”) is heard on the soundtrack instead.
