A female-fronted, high-energy modern rock unit based out of Ashland, Kentucky, Hydrogyn splits the difference between old-school, hook-driven hard rock and groove-laden alt-metal. Founded in 2004 by guitarists Jeff Westlake and Jeff Boggs and powerhouse vocalist Julie Westlake, the band released its debut album, Best Served with Volume, shortly after forming. The LP caught the attention of Pepsi, who endorsed Hydrogyn and helped to land them a key slot at the 2005 NASCAR Chevy Rocking 400. Subsequent albums Bombshell (2006), Deadly Passions (2008), Judgement (2010), and Private Sessions (2012) helped to further establish Hydrogyn as one of the East Coast's premiere modern rock outfits, charting multiple times on the Billboard Heatseekers chart and touring heavily both at home and abroad. Julie Westlake left the fold in 2015 and was replaced by new vocalist Erica Parrott, who made her studio debut on 2017's Redemption. ~ James Christopher Monger
