"Jason Crest's strong use of keyboards pointed to some similarities with the more successful Procol Harum, but at their best they came out with some unique and satisfying offerings. Black Mass is excellent, slightly crazed but very, very good, however there's an awful lot more to JC than that. Aside from a few familiar cover versions that don't add a great deal, their own songs shows an imagination and verve that I couldn't help but wish we got to see more of. Psych buffs should cop an earful, but anyone who likes a little plush, if occasionally batty, late 1960s pop will find a lot to love here"
