So I called up at Poo-Bah in Pasadena today, really nice folks and great store! I've been following the label sometime and along with labels such as All City and Stones Throw, they are really pushing forward the left-of-centre instrumental hip hop sound (that's the foundation of my doc.) with a diverse and exciting roster of artists. I'm going to call back next week to conduct proper interviews with Ron and Ras and also check out a Beat Soup instore.
