In Starkid's first production, Little White Lies, Brolden played Zach.
He, along with the Langs, wrote AVPM. He didn't act in that musical, but helped write the musical that started it all :) He has also helped write all of Starkid's shows and has helped direct a couple as well.
In A Very Potter Sequel, he played a hilarious Remus Lupin.
In Starship, he portrayed both Junior and Veeto Mosquito.
For Holy Musical B@man! he was Superman opposite Joe Walker's Batman.
In A Very Potter Senior Year, he played Hagrid contributing to one of the funniest moments during the show, when Darren as Harry sits on Hagrid's lap. Darren could not keep himself together and it was hilarious!
Brian is also suspected to be the one who operates @TeamStarkid's twitter and facebook pages. He is often the one who speaks (narrates?) during Starkid's announcement videos. He'll be a part of their sketch comedy show Airport For Birds, which starts this weekend in Chicago. Can't wait to go see it!!
