Radkey is a band of brothers. No, really — that's not a figure of speech: They're blood relations. They're also completely badass. Once you listen to the siblings — Dee, the oldest at nineteen, sings and plays guitar; Isaiah, seventeen, sings and plays bass; and Solomon, fifteen, plays drums — get down (dial up the act's "Cat & Mouse" video on YouTube), you'll be instantly sold and subsequently convinced that the "rad" part of their name isn't just a coincidence. The Radke brothers, who hail from St. Joseph, Missouri, were weaned on their adopted dad's record collection, and the three possess a proficiency that belies their age. Playing their first show in Denver, these boys are bound to leave the Mile High City with a bar full of new fans.
