“I love BU2B for its heaviness. It’s huge in the old Zep way – it’s got that big, blues-oriented riff. The chorus is very energetic, and the sentiment of the lyrics really sets it up for what’s coming.

“For guitars, I used a ’59 Les Paul and a Tele, and it’s one of the songs where I layered them. There’s probably six tracks of guitar.

“I recorded a new opening that wasn’t on the version we put out last year. For people who don’t know, mixing can be terribly tedious – it’s hurry up and wait. Ideally, you want to be out of the room and come in when the mix is ready so that you can be very objective about it.

“Consequently, there’s a lot of sitting around and ‘Hmm, what am I going to do today?’ I had Logic set up in my hotel room, and I was goofing around and doing some writing. I had a few guitars – there was one of my Axcess models and a Martin I borrowed from the Guitar Center – and I got a mic. We had talked about doing this little segue, so we stuck the mic outside my balcony and recorded some background sounds: Los Angeles in the morning, cars going by, stuff like that.

“With the balcony doors open, I did a little guitar pass, and then Ged did his vocal thing. We messed around with a few effects and created the piece. It was all done very spontaneously in just a few minutes in my room.”
