On a fretless electric playing in a trio doing Chitlins Con Carne, Kenny Burrell. Nice dynamics, vamps going on, wasn't sure it was ever going to end -- guy on guitar (his gig/he pulled me in for this) looks to me, tells me to "take a solo." Not at all prepared for that, been running the groove for what seemed like the last decade, and jumped in to fiddle around, make stuff up as I go for a run of the 12 bars. Drummer locks in perfectly, guitarist wants more .... great, what the f did I just do? More fiddling and vamping, right notes, wrong notes, no idea. It was strange, awkward, and fun as hell. No doubt, I felt like I was on an runaway roller coaster. Here's the thing, until this trio scenario I got into (and really love), there was never a need or desire for me to take many solos, I am just a side guy laying in a groove most of the time. Ironically, the closest and more recent I've come to this soloing business is when I am doing Blues; the dynamic drops down, it is me and the drummer -- running together on the progression, guitar or keys accent 1s, that sort of thing -- but they are almost always the same lines as the tune. So ... yes, I feel the need to bone up on possible "take a solo, man" directives, and that's where you come in. Can you please point me in the right direction for building "pull out of your back pocket" phrases and ideas so that I can hang, but I know that what I did was right? In other words, as exciting as a runaway roller coaster may be, I'd rather have some idea when the next drop is coming. Thanks, in advance, for any thoughts here.
