The great Jaki Liebezeit plays on this track.
Knew about the band, but I only just found out about Jaki and Hugo's involvement with Phew when I was looking at their catalogs.
Same for Jaki's role on this European free jazz classic
Honourable mention: Liebezeit's dank drum solo at a Can show. Not sure how true it is but one of the comments says that he was carrying the show while they fixed a power outage.
