According to rock history books Heavy Rock as a style grew out of Progressive Rock sometime in the early 70's.Trend setters were Deep Purple and Black Sabbath. What most reference books fail to mention is a band who were in every respect as innovative, talented and forward looking as the aforementioned. This band was WARHORSE. Formed in 1970 around bass player NICK SIMPER (DEEP PURPLE),Warhorse from the outset looked to become perhaps the most important of the new bands around at the time. During their 4 year career Warhorse managed to produce 2 albums both now re-released on Angel Air with previously unreleased bonus tracks. Rare hard rock with a psych edge.
