Lee: You guys really sound in the pocket on the new stuff. Did you record in the same room, or was this a file-trading process?
Sheehan: We were in the same room for six days and did all the basics. We spent more time of in the mix and some lead vocals.
The lion’s share, 90 percent, was done in six days in Ocean Studio in Burbank. I had just done another record a week prior and did Mr. Big there without even moving my gear. Paul and I were in a separate control booth, both Matt [Starr, pitching in on drums for the current tour] and Pat were in there doing drums.
Lee: What was that other project you mentioned, the unnamed one?
Billy: It was another project, which is yet unnamed [this writer suspects the project could be Mike Portnoy’s prog-metal band with Derek Sherinian]. So in the week prior, I got used to the neighborhood and all the nearby restaurants.
We had no time for that with Mr. Big. We had to hustle to get it done in six days. We were doing two or three songs a day. We needed one more some toward the end. We wanted to get at least 11 songs on the record and we managed to hit that.
