Disc 1 contains the eleven stereo tracks in the same sequence appeared on the vinyl album in 1971 (MDF 33/50) and on all the international issues (see the record sleeves on pages 10 & 11) in a digital restored and improved version. Disc 2 contains the film versions and alternate takes which see the light here for the first absolute time in full stereo (track 13 appeared as bonus track on the 1998 CD re-issue MDF 301 but at the time only in a mono mix, while now it is presented in full stereo). Tracks n.14 and 15 were the rare alternate versions issued only on a French compilation. Leone and Morricone's fans will discover great alternate takes of the album tracks such as "Mesa verde", reprised with a more pop tone and also with an epic trumpet, a totally different take of "Invenzione per John", the stunning variations of "Marcia degli accattoni" and the reprises of the main themes in an atonal context... in brief, there is only one word which can describe this movie and its music.
