It seems like it was just last month that Philly's Experimental/Psych/Jazz Rock band Grimace Federation released their latest EP On Velvet. Wait a sec. Thats because it was just last month (well techincally it was November, we wrote about it in December). The band recently stopped by XPN for a Key Studio Session, but not to perform tracks off their latest release, but to perform a set consisting of entirely new songs! The band stated that the recordings that make up On Velvet were approaching two years old, and another album’s worth of material was written in the downtime. Awesome. Check out the entire XPN set below.
