Yes, I wondered that too.
Listening to Peace and Blessings which has just arrived on the back of people's recommendations here - Longineu Parsons immediately stands out - someone I've not come across before. Enjoying this disc, so thanks to those who mentioned it
There was a fine Parsons compilation issued a few years back... SPACED on Ubiquity.

Yeah, that was nice - I remember having it at the radio station I worked at in KS.
