As I performed my parts tonight, I noted that I am at the top of my game. Solo music leaves room for doubt, as you never can introspect objectively enough to know for sure whether you are fully challenging yourself, but session work never deceives. The artists who's recordings I play on do not write their songs to fit my style or skill set; therefore, I know that the level at which I play their music displays the true level of skill I possess on my instrument. I worked very, very hard on honing my abilities in order to pull off a very challenging bass arrangement, and was extremely happy with the result tonight.
