21 Bottles was recorded in a practice room at the Stephen F. Austin State University, School of Music in Nacogdoches, Texas. Originally tracked in 2017, 21 Bottles would go through multiple versions before getting down the write melodies and mixing. Through the help of a few friends and SRT colleagues of Jimmy, 21 Bottles, along with the entire Say Less 2 EP, would come to reach a pleasant mix and sound quality.
