One new Sufjan Stevens song isn’t enough for you kids, so why should he stop there? For the 4/21 Record Store Day, Sufjan has teamed up with Rosie Thomas for a 7″ single. The A-side will feature a reworking of Thomas’ “Where Were You?” while the B-side will contain a new Sufjan song titled “Here I Am!” Both of the singles were recorded and mixed by Sufjan himself, and “Where Were You?” can be heard below. If his s / s / s project was any indication, Sufjan’s apparently got a lot in common with T-Pain, and “Where Were You?” nods to that.
