Adorable duo Mates Of State just released an all-covers disc called Crushes(The Covers Mixtape), so it seemed like a natural fit for Undercover. We figured it'd just be just Jason and Kori adding sweetness and light to The Replacements classic "I Will Dare," but they showed up with three other players in tow, including comedian Todd Barry on drums--he even donned kick-ass drummer gloves for the performance. Also: trumpet! Dig it.
