Drew McWeeny reviews Thunder Soul for HitFix:

“And did I mention the soundtrack? Good god, y’all. Jump back, make me wanna kiss myself. The Kashmere Stage Band was recorded extensively, both live and in the studio, and the film uses all of it to show the power of what these kids and “Prof” all built together. The film has made me go from having no idea who they are or were to being a believer in the power of the Kashmere Stage Band. There are two more screenings of this here at SXSW, and then my belief is we’re going to be hearing this title a lot over the next year, and if it turns out to be one of next year’s Oscar nominees for Best Documentary Feature, it would make perfect sense. This is exactly the sort of story that a non-fiction film can tell in a way that no fiction film can match, and it’s the charge of knowing that you’re seeing the truth that really pushes it over. I spent the last 20 minutes with a smile on my face and tears on my cheeks, and I suspect audiences will fall in love with the film as soon as some wise distributor steps up and announces the shocking idea that they actually like to earn money. There’s gold in “Thunder Soul,” and it’s the highlight of my fest so far.”
