Hey OCR, the name's Faran, short time lurker here. Now I'm in the middle of working on a project in which, as the thread name suggests, mixes Video Game and Classical music together. It's still in the VERY early stages because 1. I'm still learning the finer points of mixing and what not (I use Audacity if that helps you any) and 2. Because I don't have quite enough songs to fill up an album. Ideally I'd like to have 12 pieces at least. Here's the current list that I have so far.
Mash Up ideas
Skyrim Dragonborn theme/Toccata & Fuge
Sonic Green Hill Zone/Russian Dance
