Don Caballero - American Don
Don Caballero - What Burns Never Returns
Don Caballero - World Class Listening Problem
In that order. I downloaded "Burns" a while back and listened to it once. I found it too ADD, too hard to follow, but it has grown on me. I decided that I like American Don much more because Damon actually sticks with a time signature for longer than 10 seconds. The transitions on American Don are really clunky though, which keeps it from being a five-star album in my book.
And then there's "Listening Problem", which is a fun album, but it does feel like after Ian left, Damon just cobbled together some vaguely talented musicians to play a backdrop to his drum wankery.
All in all, a very enjoyable trio of albums recommended to anyone who's a fan of alternative rock and especially math rock (though if you like math rock you've almost certainly already heard them)
