This is a shameless plug about a college musical group. The group called the 8 Bit Orchestra arranges and plays music from video games. A volunteer group, they have played at a minecraft festival and perform free concerts every semester. The group has been around only 5 years but continues to grow. If you are interested in this music, please check out their channel.
Disclaimer: I do not own this video, it is the 8 Bit Orchestra's.
