Calamity Mod Extra Music - “Crimson Cortex“ - Theme of Brain of Cthulhu

Yet another big thanks to Aleksh for the outstanding background art! And thus ends the streak. No more daily uploads for a while, methinks. IMPORTANT NOTICE; READ THIS THOROUGHLY: THIS MUSIC IS *NOT* IN THE NORMAL CALAMITY MUSIC MOD. YOU WILL NEED A *NEW* MUSIC MOD, TITLED “CALAMITY MOD EXTRA MUSIC“ FOR THIS THEME TO PLAY DURING THE BRAIN OF CTHULHU FIGHT.
