Lots of good things on Wolfgang Dauner's 'Mood' label. Ian Carr & Nucleus, UJ&RE, Kolbe/Illenberger, Ack van Rooyen for starters. Unfortunately, most of them seem to be only available on LPs - although the UJ&RE albums have been recently reissued as 2CD sets in Germany.
Of the above I particularly recommend the Ian Carr LPs and the Ack van Rooyen 'Homeward'.
There's also a good duet album by Manglesdorff and Dauner which I have on a fairly old Mood CD - not sure if this has been reissued.
