I think he's f$%^ing brilliant! I've had a career as a player and just started studying with Jon last year. He has changed my playing for the better on both my electric and my upright bass. He's helped me musically and physically. I can recommend anything he writes or teaches, but if you're near New York, go for a lesson.
As for the melodic bass playing book, there are some solid concepts that are well explained for either bass. The guy played electric with Buddy Rich, so you know he can play!
His website has some videos that are great Jon Burr - Bassist, Producer, Teacher, Composer
