The thought, 20 years ago, of Boyz II Men and Nirvana having anything to do with one another might have paralyzed the pop world with fear and anger. But in front of a small audience at Philadelphia’s High School for the Creative and Performing Arts (where the RnB legends famously formed while students), members Shawn Stockman and Wanya Morris felt no hesitation or weight of historical genre divides when they ripped into an impromptu, largely comical version of “Smells Like Teen Spirit”.

The Philly-bred trio (also featuring Nathan Morris) descended upon their alma mater for a live recording of a show, Up Close & Personal with Boyz II Men, for SiriusXM’s Heart & Soul Channel 48. Blasting through classics like “I’ll Make Love To You”, “Water Runs Dry”, and “End of the Road” with the same passion and fervor as newer songs like “Losing Sleep” (off of their latest album Collide, which drops Tuesday), the verifiable men in Boyz II Men don’t seem weathered at all by their more-than-two decades in the music industry.

Collide drops October 21st, the same day that the broadcast of this taping plays on SiriusXM’s Heart & Soul Channel 48 at 5 PM. Check out a gallery of photos, as well as a video of their “Losing Sleep” performance and a rousing “End of the Road” sing-a-long, below.
