Here's a great interview by Premier Guitar with Brett. In much detail he talks about recording techniques, guitars used on True North, "the red rocker", how Dharma and the Bomb became the song as we know it today and much more.

Definitely one of the better interviews out there!

About Dharma and the Bomb: "That was my attempt at writing a surf-punk song [laughs] … it almost didn’t make the record. Before meeting for pre-production, I double-checked the song files on my home computer. I clicked on the song—which was half finished and didn't have any words because I didn’t think it was going anywhere—but when I heard it playback I thought, “God, that sounds pretty good.” So I decided to bring that one along, just in case. Even though it wasn’t entirely finished, I had the guys track it. I finished the lyrics and the melody in the studio and, for whatever reason, Greg was having a tough time singing it so I did a placeholder vocal to show him how the lyrics should sound over top the music. But he could never get it right."
