James Gunn is re-teaming up with Guardians of the Galaxy composer Tyler Bates for Vol. 2.

Tyler Bates, who scored Marvel’s Guardians of the Galaxy in 2014, is returning for the sequel.

This is good news, as music is obviously very important to this particular movie series. (Even though the music we immediately think of is obviously the tracks on Peter’s “Awesome Mix.”)

Bates has scored more than 60 feature films including Sucker Punch, Conan the Barbarian, 300, Halloween, and the thematically similar Watchmen (where, incidentally, the classic rock soundtrack also played a key role).

Gunn and Bates have collaborated on several titles in the past: Bates has scored the James Gunn-directed movies Super and Slither, as well as Zack Snyder’s Dawn of the Dead (on which Gunn served as a writer), and the collaborative experiement Movie 43.

In 2016, Tyler Bates will also provide the score for James Gunn’s thriller The Belko Experiment.

The Guardians of the Galaxy sequel is officially titled Vol. 2, after the second “Awesome Mix” cassette tape Peter Quill (Chris Pratt) discovers at the end of the first movie.

Not much is known about the 2017 follow-up, but James Gunn is clearly already in the spirit:
