Optimly, of couse, Al is right. But if you feel you may not be up to solo's, you might consider getting started with a volunteer band, with the older members handling solo's. You could fill in with needed instruments.

I have been playing as a one man band with arrangers for many years, but missed playing with a band. I decided to look in on a seniors band of 15 or 20 good old time musicians. They were a bit skeptical of accepting an electronic keyboard, but the key was supporting the band and not hot dogging it. It wasn't long before I was pointed at to solo with my layered bigband registrations.

You are probably younger, but the guys in my band are 10-15 years older than I am(66). Through my association with the band, I have picked up many leads for solo work, also.

Just a thought
