About Billy Failing
Billy Failing is a Colorado-based banjo player, guitarist, singer and songwriter. He is best known for his longtime contribution as banjo player with Grammy Award-winning guitarist, Billy Strings, as well as for his original voice, banjo playing and songwriting as the front man of his own project. With an intriguing focus on both tradition and innovation, he pays homage to the roots of bluegrass and acoustic music, while exploring its boundaries and devising a unique modern interpretation of classic sounds.
Some might say O’Connor Brothers Band is just a Rock Band at heart.... Others claim them to be something more.... Born in the heart of the Colorado Rockies, these boys combine that laid back mountain town vibe with a defiant pursuit of a sonic identity all their own. The band has spent the last decade traveling far and wide with one sole purpose: to prove to the people that there is, in fact, something new to be discovered in the world of music. Playing a rebellious strain of Rock, Blues, Folk, Soul, and Jazz infused music, every show this band plays will musically ride that sweet line between driving real damn fast and crashing the car into a bridge embankment... and they haven’t crashed yet.
