Cello Playing Duo Channel Iron Maiden in Their Cover of “The Trooper”
2Cellos is a couple of dudes that have been around for a few years now. Most of their popularity stems from their classic rock covers, which are always on point.
They put out this mashup of the "William Tell Overture" and Maiden's "The Trooper" over a year ago but I just found it. It's great and it rocks!
