It is not one is better than the other, but what playing with other musicians offers. There is a point of excitement when you know something special happened and that can only happen with two or more musicians are playing. We always called a high. It just happens and you can not create it.
When the tenor sax took a solo I would be playing my guitar with purpose, I was adding to what he was doing I was completely involved with his feel and his direction Here is where the magic begins.
Playing a keyboard (solo, one-man-band) has its own beauty, I enjoy it. Heres a word picture:
One-man-band On one gets in the way the drummer does not pick up or slow down it sounds the way I want it to sound more dollars. (grin)
Two or more musicians I hear another view what he is doing brings out musical emotion in me I have someone to ad to You can talk about the song you just played.
I guess from my post you can see that I miss the four/five guys I played with. IT WAS FUN.
