Tom and Jake at VIMTV are an up-and-coming duo in the YouTube music reviewing community. Their critiques may not always very poetic or sugar-coated, but these guys have some good chemistry. They're always honest and open about how they feel, and that's the mark good critic. Even when they're slagging a piece of music I really like, I still dig their humor and passion.
I interviewed them via Skype, and they had a lot of great things to say about music, the work they do, the future of VIMTV, and using video to review music.
