Kindergarten Heart is Shaina Hayes' follow-up to to coax a waltz, released independently in 2022, and her first release with Bonsound. On both albums, the singer-songwriter worked with Francis Ledoux and David Marchand (from the band zouz) who co-produced the record. Together, the three worked to gently weave elements of nostalgia, wonder and lightheartedness into this collection of songs. The result is a sophomore album which is both whimsical and earnest.
