Just out of curiosity, where did you buy the the MBV that lets you return opened records because you don't like them? A regular store? I haven't seen it anywhere but his site via mailorder, hence my not having it yet, which increases my curiosity.
Also, not sure if you've listened to much Autechre, but if not then you might want to before investing in one of their LP's. Somehow your reaction to MBV makes me question whether you'd like them very much. If you've heard them and like them, pardon me and carry on, because I do love them myself.
Lastly, I've always really liked that Beck album, and I'm sure the MFSL LP probably sounds amazing. Probably the only Beck I particularly like, actually, although Mutations was pretty decent too I guess.
Might as well give my 5 recent albums while I'm here:
Autechre: Exai (LP)
Charley Patton: Complete Recordings Vol I (LP)
Andy Stott: Luxury Problems (LP)
Ennio Morricone: Morricone in Colour (4xCD)
William Tyler: Impossible Truth (LP)
Actually the last two I don't have in my possession yet, I just ordered them, should get them next week.
