"The First Seven Days is an album recorded by jazz musician Jan Hammer in 1975. It features extensive use of synthesizers, including the synthesized \"guitar\" parts (as on his follow-up album, Oh Yeah?), with the record jacket stating, \"For those concerned: there is no guitar on this album.\" it is considered one of the pioneering works of acid jazz. Other instruments used are grand piano, electric violin and percussion.It is a musical telling of the Genesis creation story."@en . . . . . . . . . . "The First Seven Days"@en .
