Before Opus Dai, there was O.H.M.
They consisted of almost the same lineup with an extra female vocalist. There songs are still just as great. They made a video for Sora – personally I like the newer Opus Dai version better but still worth checking out.
They’ve done a cover of Tool’s Bottom, which if you are really eager, can buy from amazon here – appears on yet another tool tribute cd. To hear the vocals of Opus Dai infused into a great Tool track is a humbling listen.
