We're all over the place on this week's podcast. Mike is back, and the guys try answering how much riffing is prepared vs off the top of the dome. Aldrine equates riffs to catchphrases and new vocabulary to try out in sentences. Mike give a brief history lesson of riffing, and explains the different levels of difficulty of riffs/improvising. A UUer asks the guys what they think about the origin of Mele Kalikimaka which leads the crew to discuss the perception of Hawaii in the 20's, and stereotypes people have about music from different cultures. Someone else ask how much songs you should know to perform while another member asks if using Tabs is a crutch? It's a grab bag of tangents and references.
