At most of the joints I play, the patrons want to hear the melody...I can mess with the chords all I want(within reason) but, they don't seem to like too much wandering away from the melody.
Which is good thing, considering I only have a bunch of well practised(and well worn) licks that I generally use when "improvising"...occasionally I'll learn a new one, but I love having the old ones to fall back on, and work away from.
That doesn't mean I don't enjoy listening to well played improv...but, I guess even then I have my favorites...Bill Evans heads the list...Diana Krall is a relatively recent addition....a feast for the ears
and the eyes.
I remember seeing her playing in a hotel lounge while I was on a Yamaha seminar, waaay back...I had said to one of the guys, that she was something else...she couldn't have been much over 20, maybe younger...and that she was probably going places with that talent.
She sure did...the "Live in Paris" DVD is my favorite concert.
There I go...digressing again.
