I thought they broke up because Ed left to write/tour with I Killed the Prom Queen after Michael Crafter left IKPQ (or maybe he left because his drummer left?) . Wasnt this the band Ed was in b4 he helped them write "Music for the recently deceased?" Then after that Ed went back to UK to start Eternal Lord. I could be wrong but that was my understanding.
They did not broke up, the account of Ida Wave on Myspace is still active, so if they would break up, I think they would right it down there. Also, the Members are still only Ed and his friend Chris. And if you would know them, Ed was formally a guitar player and I think Chris is able to play Drumms, so they could do this without an another Drummer.
