A maxi single or maxi-single (sometimes abbreviated to MCD or CDM) is a music single release with more than the usual two tracks of an A-side song and a B-side song. The first maxi singles Mungo Jerry's first single, "In the Summertime" was the first maxi single in the world. The term came into wide use in the 1970s, where it usually referred to 7-inch vinyl singles featuring one track on the A-side and two on the B-side. The 1975 reissue of David Bowie's "Space Oddity", where the featured song is coupled with "Changes" and "Velvet Goldmine", is a typical example. By the mid-1970s, it was used to refer to 12" vinyl singles with three or four tracks (or an extended or remixed version of the lead single/song) on the A-side, with an additional two or three tracks on the B-side; the B-side was initially used by DJs. Later, in the 1980s, a typical practice was to release a two-song single on 7" vinyl and cassette, and a maxi-single on 12" vinyl. These first 12" maxi-singles were promotional and mostly sent to discotheques and radio stations. Examples of such promos—released at almost the same time in 1975—are Gary Toms Empire "Drive My Car", Don Downing "Dream World", Barrabas "Mellow Blow", The Trammps "Hooked for Life", Ace Spectrum "Keep Holdin' On", South Shore Commission "Train Called Freedom", The Chequers "Undecided Love", Ernie Bush "Breakaway", Ralph Carter "When You're Young and in Love", Michael Zager & The Moon Band Feat. Peabo Bryson "Do It with Feeling", Monday After "Merry-Go-Round", The Ritchie Family "I Want to Dance" and Frankie Valli "Swearin' to God". Salsoul Records made 12" maxi-singles commercially available for the first time in May 1976 with the release of "Ten Percent" by Double Exposure (SALSOUL 12D-2008). An earlier 12" catalog number from this label is "More" by Carol Williams (SALSOUL 12D-2006), but it was released later. Cassette maxi singles Occasionally, a cassette single was released in two cassette formats simultaneously: a traditional Cassette single with two tracks and a cassette maxi-single with four or more tracks, generally remixes. This practice was experimented with in the 1980s. Example: Debbie Gibson – Out Of The Blue (cassette maxi-single) released by Atlantic in 1987 in the USA. Includes four mixes: 1. Club Mix, 2. Bonus Beats, 3. Drumapella, 4. Dub version. This was packaged in a 12" × 3" cassette maxi single longbox (with
