Originally released in 1971, "Hard Rock" is one of the most sought-after albums from the American Christian rock underground and a genuine hidden gem of the early 70s heavy psych scene.

Built around powerful male and female vocals, blazing fuzz-wah guitar and a raw, energetic sound, Earthen Vessel created an album that often feels far removed from the typical expectations of contemporary Christian music. The songs combine hard rock intensity with psychedelic flourishes, drawing comparisons to bands such as Jefferson Airplane while occasionally venturing into rougher, proto-punk territory.

What makes the album particularly appealing is its combination of strong songwriting, passionate performances and heavy guitar-driven arrangements. Whether approached as a Christian rock rarity or simply as an outstanding hard psych record, "Hard Rock" stands firmly on its own musical merits.

This Guerssen reissue is sourced from the original master tapes and includes an insert with liner notes and rare photos. Essential listening for fans of heavy psychedelic rock, fuzz guitar and obscure American underground albums.
