It was totally intense and exhilarating. The clock ticks and time = money.  We came in prepared, and the "live in the studio" stuff seemed pretty tight.
The backing vocals were tricky.  Not sure how well they came out.  I guess we'll figure that out in the mixing phase.  Almost done with tracking - we're thinking one more session to add a saxophone and maybe harmonica. 
Then it's mixing.  Should be an interesting trip...
