An edgier side of Colbie Caillat is filling the Garden, the Denver Botanic Gardens that is. The Grammy-nominated singer-songwriter's latest album, Gypsy Heart, introduces a shift in sound for the acoustic folk-pop star—its heavy production and use of electronic melodies set to lyrics about natural beauty and breakups provides a more upbeat, edgy collection of songs. Listen to new tracks such as "Try" and "Blaze," as well as older hits like "Bubbly." Pop duo Alex & Sierra, winners of the final season of the X Factor, open. Wed 7 p.m.
