We start with a little follow-up about the NYC marimba schlep anecdote from ep 1 and fleshing out the concept of instrumental "doubling". Early on, a guest conga player appearance challenges the guys' ability to stay on track. The conversation takes a random side trip to answer the perennial question about what a movie set "key grip" is and Pete throws out the concept that musicians tend to fall into one of two categories: readers or practicers. That idea gets explored through Andy's performance watching preferences, tangentially through Josh's show-learning abilities, and Andy's part-assigning technique, hammer dulcimer and vibraharp experience notwithstanding. Finally, our guest, non-brush-using conga player makes a brief, on-mic appearance!
