¡Uno! featured a guitar solo on nearly every song... what’s going on?!

“The funny thing is on this record I actually play more guitar solos than I have in years. That’s kind of what came out of the room while the four of us were playing together. The more I was doing it, the more they’d encourage me to keep doing it!

"I always had it in my arsenal of guitar playing, if you will. I used to use it live, but not really, and on the very early records I did it more often. On ¡Dos! And ¡Tré! it gets even more intense. It’s more just about having fun:I wanted to be able to pull out these guitar solos on these records and just go for it.

“On American Idiot, I started getting into more tasteful, appropriate things. But, this time, I almost wanted to play things that were deliberately not tasteful and inappropriate! So, we were just like, ‘F**k it, let’s f**kin’ tear up a f**kin’ guitar solo right now!’ I kind of wanted to make Zakk Wylde’s favourite Green Day record, you know?”
