"Best Debut" of 2011 according to Matt Blackall...and somehow the first reviewer to realize that the song on side B is a cover:
"There were lots of interesting debuts this year, but I found myself going back to this one a lot more often than most. Mix one part crazy sound experimentation with one part loud and fast punk rock and you get Den. For the whole album, they manage to mix both of these aesthetics together in a way that makes them seem inseparable. Throw in an inspired cover of Sabbath’s “Symptom of the Universe” and you’ve got one hell of a tape. Den hasn’t released anything since this tape came out, so hopefully we’ll be hearing something new from them in 2012."
And, oh yes, you will be hearing something new in the near future.
Also, Travis Bird's favorable review.
