“I don’t want something too rocky – just Yeshivish”
Uhhh..you do realize that by Yeshivish you mean more “klezmerish” which was the rock music of the goyim back in de alter heim.
So by trying not to be goyish..you are still being goyish. And if goyish music is an issur of some sort, it might as well sound like it came from this century rather than the soundtrack to a pogrom.
