No backtracking here. If it turned out that I like them, I tell you all where you could stick your musical tastes. Alas, we agree this time...
Epitonic is a great place to find a lot of indie/post rock stuff. I learned about Unwed Sailor, Tarentel, Pele, Mogwai, Billy Mahonie, Tommy Guerrero, Turing Machine, Tristeza, The Album Leaf, Oma Yang, The Roots of Orchis, The Letter E, Magnetophone, and literally dozens of other bands there.
