It feels a lot like Throwing Muses, while being very distinctly it's own sound. I guess it's not too surprising, considering that Kim Deal originally cofounded The Breeders with Tanya Donelly, one-half of the creative heart of Throwing Muses (the other half being Kristin Hersh, who still consistently hits the top of my list).
I seldom grab two albums by the same group, as the ocean of music is quite big, but I might reconsider for The Breeders. Also, Kim Deal was in The Pixies, so I'll probably be picking up Surfer Rosa or Doolittle.
After a few more listens of Mountain Battles, I've concluded that the first half of the album is great. The second half is just okay (sometimes good). Still, a great half-an-album is like a great EP, and the rest is just sorta bonus tracks. It doesn't really hurt to have 'em.
