90% of the time for me, when I'm recording, it's the latter - most of the tunes on my records are 1st or 2nd take improvs, that i've then had to go back and learn to play live.
On the new record there were a couple of more composed things - Behind Every Word took quite a while to get right, and the final version is very different to how it started out. Scott Peck was an improv that I'd recorded in 2005, which a friend reminded me of when it came time to do the record, so I went back and learned it. Deeper Still started out as an improv, but it took me LOADS of takes to get the damn thing in tune!
on Grace And Gratitude, I think the title track was the only one that was actually played more than once. So the ones of that that I do live are the ones I've been able to learn - I'd love to play 'The Space Between The Silence' live, but i've NO idea how I got most of the sounds on it!
I'm getting more into more structured composing though, especially with the arrangement possibilities presented by the Looperlative.
cheers
