Danielle DeCosmo is a Florida born singer songwriter who has been performing professionally since she was 8 years old. Her first full length album, “Heavy is the Heart”, released March 2016, is about 10 years of her life. The songs are sometimes personal, yet somehow seem to be universal in the human experience. DeCosmo's music is Thievery Corporation meets Billie Holiday, richly enhanced by deep lyricism.

“She is small in stature, but has a big, big voice….think Susan Tedeschi. She was born way too late to be a torch singer at the Copa, but her voice will remind you of those silky 1940′s vocalists.”
―Steve Hart, Amelia Island Blues Fest 2010

“DeCosmo, vocalist for Boss Lady and the Company, came to 6th Street when the band had an opening for a lead singer. At Friday’s show, with her hair pulled back and dressed in a modest black sleeveless frock, she didn’t resemble the bikini-top-wearing, belly-baring chick from Boss Lady and the Company. That iteration of DeCosmo is something of a local legend. The singer lost nothing in shedding the sexy for the demure. The modest attire meant that the voice had to stand on its own and it did, alternately gliding, swooping, sailing, and rocketing through a set list comprising R & B classics and original material. ”
