Rock & Roll Shin-Soo Choo has reformatted to shorter episodes and full webcam video - once again - on our YouTube channel! In this episode, we discuss Lady Gaga's David Bowie tribute at the GRAMMYs, the Grateful Dead tribute by indie bands and the Pitchfork Festival lineup slated for July in Chicago. As pitchers and catchers report to Spring Training, we also eagerly jump into prognostications, fueled by Jonah Keri's SI.com MLB preseason power rankings.
