Both Isaac and Jeremiah have been interviewed by Relix Magazine. The article, posted earlier today, touches on a few subjects such as the album delay, the amount of work that went into it, and the chemistry that still remains between the two.
They both also embellish on information that has come out recently on how the recording process was stopped and restarted numerous times. Isaac also talks about Ice Cream Party Studios, the studio they built in 2012. Both mention that the band amassed around 35-37 songs during these sessions, with Jeremiah adding "...I promise our next record will come out sooner. We have a bunch of songs and we'll probably rework them. They are good-they're just not finished. We might put out something really strange next."
Isaac also talks about Eric, and says that there was no drama involved in him leaving, just adulthood.
"He finally had enough," Brock says. "He has three kids. He didn't feel like leaving his house as much as is required. He left right before we started recording, but some of his writing still exists throughout the record. Making a record without him was really fucking hard."
It's an interesting read, with many more points that I've not touched on, find the link to the full article below.
