Well, after 2 albums in 1 year, it took me about 3 years to get to the next. Funny how life changes. We now had 2 young kids running around the house and my guitar time was significantly different at the time.
Instead of being able to play for a couple of hours a day, I had to scramble to find a few minutes whenever possible. This made me work on more elaborate but less improvised arrangements. I spent about 6 months playing 3 or 4 tunes, then went to the studio and recorded them. I repeated this process twice more, and 18 months later had the album finished. Of course this meant I could barely remember how to play any of the tunes from previous sessions.
I also neglected to write any of them down at the time, and only got to a couple of them a little later. Which means I only have guitar arrangements to the original songs and 3 or 4 others. Someday I will painstakingly sit down with the album, figure out the songs, and write them out... hopefully.
