Greg and Tom Z. both pitched suggestions for Mason Proper, so it seemed, um, appropriate to check the band out. (Sorry.) In that Nick Hornby sort of way, they had me at the album title — “There is a Moth in Your Chest.” From Ypsilanti, MI via Up North, Mason Proper sounds unlike any of the other megabytes tripping lately through my almost-dead iPod. (It keeps cycling through the songs without actually playing most of them. Occasionally I’ll get half a song or so.) Crazy pop? Art rock slapstick? Just categorizing these tunes seemed like a waste of time. Expect obscure lyrics, sweeping melodies, noise, dream-pop buzz, and the kitchen sink, too. After hearing My Brightest Diamond and Mason Proper, I’m wondering what else Ypsi has to offer.
