I have to be honest. I have never been a big jazz fan. I think it's because I get bored lsitening to someone do a 15 minute solo. I have always admired the musicianship of jazz and blues artists but I am more a fan of rock, blues and country. My favorite players are Paul McCartney, John Entwistle, Craig Macregor of Foghat, John Deacon, Tom Hamilton and Marcus Miller because I love his tone. However, after seeing my first jazz concert, I have a new appreciation for it. It was one of the best shows I have ever seen. I am a self taught musician who was accepted to Berklee in the early 1980's but never attended the school. My keyboard player has 2 degrees from Berklee and has told me that I am the best in the pocket player he has ever played with. However, my improvisational skills are severely lacking. Any advice? I have been playing for close to 30 years but always in structured settings. I am looking to expand my repertoire. Thanks.
