Really enjoying these tracks off the new MBV:

Love Goat, and like Head and Liar as well although they seem less consistent. I've been trying to explore various styles of noise rock, but they and bands similar to them are what I always find myself going back to. Also listened to The Birthday Party because of constant comparisons between the two, and what I have there (Junkyard and the Mutiny/Bad Seed EP compilation) are great as well.
I've listened to a little Shellac but not much. I kind of associated them more with a mellower (speaking very relatively of course) Fugazi kind of sound, but someone else brought them up recently and I think that I ought to at least listen to their first album in full. I have Battles' Mirrored album and like it quite a bit too. Usually I don't go for the repetitive/minimalist type of math rock but I think the quirkiness wins me over.
One very Jesus Lizard-y band I just recently came across is Circus Lupus, and while I haven't heard any albums in full yet and am not sure if they cross the line into imitation, I do enjoy what I've heard a lot.
