Moving Waves brought Focus international acclaim and a hit on both sides of the Atlantic with the radio edit of the bizarre rock rondo Hocus Pocus. This rock classic consists of Akkerman's striking guitar chord sequence used as a recurring theme, with quirky and energetic interludes that include alto flute riffs, accordion, guitar, and drum solos, whistling, nonsensical vocals, falsetto singing, and yodeling. This album established Van Leer and Akkerman as composers who could appeal to both progressive-rock album listeners and radio single buyers.

This is a 1971 US pressing with red text on the back of the cover. Signed by Thijs van Leer
