BadBadNotGood IV

It is also the band's first album to feature longtime touring partner and collaborator Leland Whitty as a formal member of the band.

In an interview with Howl & Echoes, the band described IV's conception and recording process:
Since we recorded and released III, we’ve been writing tons and tons of stuff inspired by all different sources. We were touring heavy after the release so we got exposed to a huge range of really talented artists at different festivals, and had many friends putting us on to great music from the past also. We wrote a whole batch of songs that were instrumentals early on in 2015, and recorded a few of them. After sitting on those for a while we decided to start from scratch, so starting in fall 2015 we began writing and recording the songs that became IV. We had a bunch of sessions booked with the very talented artists that appear on the album, and had some amazing creative times with them. There was no defined direction when we started, and we reached a point when we had so many different styles of song that we didn’t know what the album would even sound like all together! For a while we were still going to make it an all-instrumental album, and then we tossed together a salad of some of the amazing featured tracks, along with some instrumentals and it ended up working out!
