Mike McCready who helped to score the original Horrible Bosses movie, has joined Christopher Lennertz with his friend, Stefan Lessard, from the Dave Matthew's Band to score the sequel as well, even recording much of it while on tour.
Lennertz had this to say in an interview with We Are Movie Geeks:
“The goal for the score for Horrible Bosses 2 was to be as rock-n’-roll as we could be. We wanted to make sure it sounded authentic so we approached it like a record as opposed to a typical scoring session. I had Pearl Jam’s Michael McCready and Dave Matthews Band’s Stefan Lessard recording while they were on tour to give us an authentic vibe that was appropriate for the movie,”
