ECM (Editions of Contemporary Music) is a jazz and Western classical label that features acoustic and electronic artists producing eclectic versions of contemporary music.

ECM's catalog spans from contemporary works (Steve Reich, Arvo Pärt, Philip Glass, Kronos quartet...) to experimental and electronic jazz (Nils Petter Molvær, Pat Metheny Group, Jan Garbarek...).

The catalog includes over 700 recordings from 35+ years of producing works. Since 1969, ECM albums have been acclaimed for their outstanding music, creative production, and exceptional sound quality.

ECM releases with the (additionally mentioned) cat# format XXX XXX-X are distributed by Universal Music Group worldwide. However, in the US, during the early 1980s, the label was distributed by Warner Bros. Records, and 1994–1999 by BMG, returning to Universal Music in 1999, after the merger of the MCA and PolyGram families.

BMG-distributed US releases from the 1990s take the original ECM number and become 78118-2XXXX-X, the last digit denoting format. This does not, however, apply to the JAPO or WATT releases, which use the same 78118 prefix.
