I actually really like this film. Its quirky, strange and funny and while sombre in places and not quite sure about the message it's ultimately trying to deliver, it was a fun little watch.
Frank is a musical genius wearing a big head mask. He never takes it off. The protagonist lucks across his band desperately needing a new keyboardist and joins up for what he thinks is a short little gig but is an album recording session. It all comes to a head at SXSW.
