I know a few people here have read this book. It's on the reading list for my improv class, and a lot of people also recommended it to me. It turns out my teacher for improv knows Kenny Werner personally! Crazy. Just read the first three chapters, and I can definitely relate to the low self-esteem, and feeling worthless when hearing a player better than myself. The five minute finger exercise he mentions is interesting. Not tried anything like that yet (not entirely sure how it would translate to bass), but I thought I'd take something from it and jam along to a song differently than usual. First song that came up on shuffle: Dark Shrines by Muse. I don't know the bassline to the song but I thought I'd jam along. I didn't really pay any attention to figuring out the exact line; just played around not really giving a crap how it came out. It sounded way better than when I usually jam along to songs! I hadn't warmed up, and my hands were cold (hurray for my crap house), but I was coming out with all these licks that sounded great; stuff I wouldn't have played usually, and some faster stuff than I'd usually think I could play. Seems like this book is helping a bit already!
