O Cara Mia, Addio - Turret Opera by ArrMcCardle published on 2011-07-26T04:38:54Z My arrangement of the turret opera at the end of Portal 2, where they bid Chell farewell. I have different scorings for Brass choir, Tuba Ensemble (EEETTT) and Bugle Choir. Sorry about some distortion, I tried a new mic setup and It didn't turn out the best. Anyway, please enjoy :D Genre Game Music
