Otiel has some great things to say about music, not just scales and chords, but the bigger picture stuff that every musician has to deal with, things like fear, being self critical, practicing, and life as a musician. He seems like a pretty deep guy and he nails it as far as how the things that hold us back have nothing to do with not knowing a scale or chord, but we become our own enemies. Good stuff.
And oh yea, he sounds great on his six string. Otiel has his own band called the Peacemakers, and he also plays with The Allman Brothers.
