Influenced by both the popular music of her era, such as folk, R&B, and rock 'n roll, to music embraced by her parents (including Torch icon Julie London), she grew up in a music loving family. Her brother, Scott Crownover, is a self-taught guitarist (whose influence led her to pursue a music career) who first introduced her to acoustic music including James Taylor, Carol King, and others.. Her sister was a devout fan of Motown and R&B, especially the Supremes. After being involved in music and theater in school starting in her elementary years, she began singing around the Jacksboro Highway blues circuit in Forth Worth, Texas, at the age of 14 performing in acoustic folk and blues ensembles.
After relocating to the Boston area in 2000, Sunny eventually became the featured vocalist with 2120 South Michigan Avenue, a Boston based blues band led by Harvard professor Charlie Sawyer, which led to her fortuitous meeting with Duke Robillard in 2008 during a symposium at the Harvard Extension School in which they were both performers.
That meeting led to an ongoing collaboration of projects between Duke and Sunny beginning with the formation of Sunny and Her Joy Boys, a five-piece acoustic jazz and blues ensemble whose 2009 release on Stony Plain Records titled “Introducing Sunny and Her Joy Boys” was received with critical acclaim from press and critics alike.
She was also featured on Duke’s grammy-nominated “Stomp! The Blues Tonight” (Stony Plain, 2009), followed up by “Tales from the Tiki Lounge” (Blue Duchess Records, 2010), which debuted in the Top 40 of the Americana charts and continues to sell online today despite being out of print.
In her solo debut, “Right Here Right Now” (Blue Duchess Records, 2012), she returned to her contemporary roots in a rocking, bluesy roots based recording that hit the airwaves arriving in the top 20 of the Living Blues chart, garnering praise from critics and fans worldwide.
In 2013, she appeared as a guest on the lead track “It's All About Love” of Nuno Mindelis II's “Angels and Clowns” (Blue Duchess Records, 2013), which became a huge hit in Brazil and beyond.
With the two new tracks, “Amapola/Moon of Manakoora” (Meadowtime Records, 2015), Sunny takes you back to the Tiki Lounge with The Duke Robillard Orchestra with two new renditions of songs that will transport you to another place and time. Featuring the legendary American jazz tenor saxophonist Scott Hamilton on “Amapola”, and Hawaiian steel guitarist Chris Davis on “The Moon of Manakoora”, this release is sure to please fans of jazz, blues, and swing - and Tiki. Sunny says, "Music has always been my greatest passion in life. I grew up listening to all kinds of music and knew I wanted to be a singer from a very early age. Working with Duke and the rest of these incredible musicians has made a life-long dream of mine come true".
