Circles Around The Sun's began when Casal was asked to record a handful of Grateful Dead-influenced instrumentals to be played during the set breaks at The Dead’s "Fare Thee Well" concerts in 2015. To accomplish this task, Casal assembled MacDougall, Horne and Levy to join him in the studio. That was supposed to be the extent of it. Fast forward to the music being played over the stadium's PA at the shows. The response from the audience was resounding, blowing up the internet with questions as to where this music came from and pleas for more. To appease the demand, Circles Around The Sun released those recordings as their debut album, 'Interludes for the Dead.' Prior to Casal's passing they released two more recordings, the double album 'Let It Wander' in 2018 and the EP, 'Circles Around The Sun Meets Joe Russo.'
