Let me explain. I grew up holiness so I know all about "unions on 5th sundays," campmeetings, week long tent revivals, jurisdiction, etc. Now that I'm on my own have gain my own understanding, I don't partake in those events no more. So, no I don't have to "compete" with the next musician to get some play during various services, musicals, etc. Been there, done that. All I'm saying is that I'm feel free. This is just ME. I please don't take offense to anything that I'm saying.
About the shed comment, obviously, the musicians where you are from have a different mindset. Yes, some sheds are show off sessions, but even with that, you can find some ideas from those sessions and broaden your musical perspective. Sheds are very much creative. How do you think the musicians come up with the creative licks and fills that they do. I hope that you take this next sentence with an open mind. It appears to me, that you don't like to step out of your comfort zone, which is fine, but when you don't you'll reach a plateau and never go any higher. Its like p90x. Tony Horton developed that system of training so that your muscles never get accustomed to what they are doing, ie. muscle confusion. This is so that our body doesn't reach the plateau affect. The same can be said about music. Its good to do things differently so that you can learn more. For me, I used to not like listening to music similar to Jonathan Stockstill, but at the church I currently have my membership, we sing his songs and others. With learning to play these songs, I learned how to play in unfamiliar keys such as E, B, A on the keyboard. In gospel, mostly everything is either in Eb, Ab, Db or Bb. I can now play in any key with no problem. Why, because I haven't limited myself to just the norm and my comfort zone.
