In a recent interview with Alternative Press, Bad Religion guitarist Brett Gurewitz discussed the band's next album, whenever it may arrive:
We put out one record a year between '87 and '94--we put out seven records. So that's what we like to do. When I was a kid growing up and I was a fan of bands, bands used to put out a record every year. It was like writing songs was part of your job as a musician. We were always writing; we would always put out a new record.
I don't think 13 months is a short time to wait for a person who's a fan. If I'm a fan of a group, I consume their record greedily and I'm ready for more in six months. So the reason is, I feel that it's a band's job to put out records and not wait forever. It's something you do for the fans, and it's something you do for yourself as an artist.
Whether we can do it remains to be seen. I'm super busy here at Epitaph and Greg is a professor at UCLA now, and so it's not as easy as it used to be to find the time to do a good job and write an album a year or so. The goal's an album for every two years and hopefully we can do it.
