I am undertaking a lot of new guitar concepts to spice up my Blues licks. In particular I am finding Fusion licks very versatile and even some choice Jazz lines and rockabilly concepts a great crossover to expand our writing ideas. A main source for me right now is Mike Ihde's 333 book. I studied with Mike back in the 80's and recently noticed he came out with this new book that covers 333 licks and techniques that cover Rock, Fusion, Jazz, Rockabilly, Blues you name it if it is guitar stuff it's in there. Mike still rocks and it rekindles my session days.
