Richard Pinhas recorded seven influential albums as the leader of French space-rock pioneers Heldon in the '70s, with a further five solo records before his six-year break from music in 1982. Since returning to the form in the '90s, he has been prolific, collaborating with such luminaries as Merzbow, Yoshida Tatsuya, Oren Ambarchi, Barry Cleveland and Wolf Eyes. The dark, experimental noise and long repetitive tracks of 'Reverse' have an intimidating first impression. But listening to the whole 50 minutes leaves one feeling purified.
