I remember when it was announced the chain was closing. I immediately thought about borrowing the video recorder at Rhino to document the place so that people could see what a real catalog record store looked like; by the time I got a little more serious about it, the store was pretty picked through. So I'm glad this exists!
I'm not sure if - beyond places that specialize in a particular style of music - there are any true catalog stores left (ie., ones where the buyers make it a point to stock older titles they considered worthy in the hopes they'd be discovered in the bins), though Amoeba here in L.A. comes close. Still have the couple things I snagged from Tower Sunset's last night...
