2010 release, the 12th album in an infamous career, Not Music is part of Tim Gane's 2007  science experiment involving improvised chord sequences played on piano or  vibraphone, over top of which were placed little drum loops. This was a new way of  writing and it yielded a bumper crop of compositions, nearly 70 of which  were boiled down into 32 new songs, 14 of which were cherry-picked  to form Chemical Chords.
