A scene from my Anthro MLP dreamscape. The metal band Flying Finger who’s core members are the grownup CMC did a series of concerts at Mount Aris while on tour. One unique facet of performing at Mount Aris was that they did two completely different concerts. They had one performance on land, and then one underwater.
 
Needless to say performing a heavy metal concert beneath the waves present several technological challenges to the road crew. However hurdles were overcome and solutions found. Also Applebloom’s drum set required extensive modification.
