This is a 1970 album by Abstract Truth, a band from South Africa.
The band features a lot of sax, and flute, but this is not the driving blues of early Jethro Tull or Bloodwyn Pig. Abstract Truth are far more laid back, almost trance-like. The CD carves a quiet groove and stays there.
But there is a lot of subtance here, and this group will make a mark given a chance. You can listen intently, or play it a few times and let the quiet groove wash over you.
Fantastic, dark cover of Donnovan's "Fat Angel."
