The Silver Lake Chorus rehearses the MacGruber theme in the Black Iris LA Studio.

We’ve had to keep this one under-wraps for a while now, but are stoked that we can finally spill the freakin’ beans. One of our primary composers, Matthew “Cornbread” Compton, has been barricaded at an undisclosed location for much of this year working on the score for the MacGruber movie.

To celebrate the film blowin’ up in theaters across the country today, and the soundtrack now available, we wanted to share this tidbit of behind the scenes footage with you. Fans of Black Iris will want to pay particular attention to Cornbread’s handiwork on the “MacGruber Theme”, also featuring a raging sax solo by Fool’s Gold’s Brad Caulkins, and the tracks “MacGruber’s Suite” and “The Perfect Number” featuring Kristen Wiig.
