I play live about twice a week and to be honest...I'm very selfish! Yeah I'll play through the song, but all I care about are my 10 to 20 seconds to shine when my solo comes up for each song! I really like what you said about pleasing yourself with your own music. We guitar players tend to be so hard on ourselves. I'm to the point where I can improv a solo and impress the crowd (not tooting my horn...keep reading!) But that's because the crowd just wants to hear music and dance AND they've never heard you play, so any halfway decent solo will sound good to them. What really makes me feel good is when I can impress my bandmates (they're the guys who listen to my solos over and over...so if I can do something new to impress them, that's where satisfaction comes from.)
