'437 Studios' refers to the Pink Hat Studios location during the recording of New Threads' fourth studio album, Threadsboro. The 'studio' was actually a 10x15 storage unit at Storage Plus in Smyrna, Tennessee.
The area became the band's final headquarters in Tennessee, with the storage facility becoming the primary location during the final phase of the Felonious Wilma cycle and the entirety of the Threadsboro cycle. The storage unit itself, #437, can be seen extensively in the music video for "There Goes My Mind," as well as in promo shots and on the Threadsboro cover itself. The storage facility can also bee seen on the single cover for "Strawberry Shake," which features a photo taken during the Threadsboro recording process. The artwork for all three Threadsboro singles ("Clean," "There Goes My Mind," and "Sunburn") feature photographs taken at the facility.
