This trio from Philly recorded 4 albums from 1970 to 1973.They were an early hard rock-heavy metal band. One of the first records I bought was their second recorded but the first one released in 1972. Apparently the first record was not released until 2011. One song from that album “Questions” was a semi hit in 72 that I heard on AM radio. That record was very Black Sabbath sounding. I don’t know what happened to it but side 2 of this best of record has 5 songs from that album
