My Sister, My Brother

Garrison Starr, Sean McConnell and Peter Groenwald had no intention of forming a band when they gathered for a songwriter's camp during 2018 in Nashville. But their composition there, "Nothing Without You" led to My Sister, My Brother. "We just hit it off right off the bat and had so much fun," McConnell tells Billboard. "We wrote 'Nothing Without You' that first day, and we were all, like, 'Wow, this is something we should do again' and we made it a priority to get back together." The trio wound up writing a half-dozen songs together at four or five subsequent gatherings back in Nashville, recording mostly at Groenwald's home studio. "We all produced, but Peter did most of the heavy lifting," McConnell reports. And he says their continued collaboration was about as easy as it was for "Nothing Without You."
