Denver Botanic Gardens has been hosting its annual outdoor summer concert series, now produced in partnership with Swallow Hill Music, since 1980. The series includes ten concerts from June through August and showcases both local and national acts in an array of genres — all surrounded by the romantic beauty of the well-tended gardens. This summer will see shows from Graham Nash, DeVotchKa, Trombone Shorty, Emmylou Harris and more. The DBG also hosts Evenings Al Fresco in the summer, intimate music experiences that take place around the 24-acre grounds.
