Sessions is a series of DJ mix albums, each album normally by a different DJ who also compiles the tracks, released by the London-based electronic dance music label Ministry of Sound.
Alongside The Annual, it is one of Ministry of Sound's better-known compilation album series.
In about 2000, the Sessions series was a joint release between Ministry of Sound and Defected Records.
After focusing on the spin-off series Chillout Sessions, which ran initially for 8 volumes between 2001 and 2003 (plus a 9th volume in 2006), Ministry of Sound "rebooted" the Sessions series with a brand new album released in 2005.
The Chillout Sessions series is perhaps the best-known "spin-off" to the series, beginning in early 2001 when Ministry of Sound started get digital mixers to mix their albums as opposed to big-name DJs like Tall Paul, Pete Tong or Paul Oakenfold.
