E2-E4, released in 1984, is a solo recording by Ash Ra Tempel/Ashra guitarist Manuel Göttsching. The album consists of a minimalistic hour-long progressive electronic track that is subdivided into single tracks according to the stage of the song. The second half of the record is notable for Göttsching's guitar playing. The album is named after the most popular opening chess move 1. e2-e4 (which is expressed in long algebraic notation). A noteworthy pun on E2-E4 exists because the guitar is tuned from E2 (the low string) to E4 (the high string).
