+1000! Man do I agree with this. Probably should be a separate thread, but yeah get out and see the music live. Unfortunately so many of the great jazz musicians from the 'golden era' are gone now. But there are still great players out there so check them out. I can attest to the live vs recorded experience, having seen many, many live shows way back when, then listening to the recordings and it's a completely different experience. The recordings are fine, but in many (most) cases, only a shadow of the real thing....go see him play. This jazz music stuff is a live art form. Records are but a snapshot in time.
You can listen to CDs, watch YouTube all day... there is no substitute for sitting right in front of these guys.
To the OP: Joshua Redmond is actually very well known for a jazz musician, and highly respected. At least as well known as Branford Marsalis. But don't worry about how well know someone is. Search out live music. You'll have more opportunity to do that as you get older, of course (until/unless you get caught up in the job/family, etc etc).
