HEAT! Fresh Kils and Uncle Fester (together known as The Extremities) are back at it again with another routine, this time blending Portishead's "Strangers" and "Sour Times" with O.C.'s "Time's Up" to create "Sour Times Up" -- not just a clever name-twist but a dope combination from two unexpected corners of the music world. Even better, the guys were kind enough to give us the honours of premiering it. The routine comes as the Toronto/Halifax duo prepare to embark on a U.S. tour to promote their new album, Instruments. Check out the routine below and read the mini-interview after the jump.
