I know you watched AVPM and AVPS. I recommend you watch other Starkid shows. For now, I recommend that you watch The Guy Who Didn't Like Musicals. The plot can't be talked about much without spoiling but it is one of their best shows and one of my favourite. It is a musical with some pretty catchy songs and the way it's performed is so well acted. You can find the whole thing on youtube just by writing out TGWDLM.
