Superb Blood & Fire selection of scattered late-seventies outings, all in discomixes. Treasures include the opener, Reggae Rhythm, with its blaring horns, originally out on Trio International; the 12” mix of Pure Ranking by Jammy, at Tubby’s; and the deadly triumvirate of Everton Da Silva productions — Youths Of Today, Don’t Let Problems Get You Down, and Mr. Bassie.
