Sometimes an act will have a following of millions on YouTube and you still haven't heard of them. Boyce Avenue is one of those acts. The pop/rock band of brothers has been selling songs and shows are the world, so you may have actually seen them outside of their billion (and counting) YouTube views.

Boyce Avenue is in the spotlight this week for a viral video that came out of partnering with a non-profit Pencils of Promise (PoP). PoP helps increase educational opportunities for children in developing regions. Digital sales of their song "One Life" will go to PoP. The music video has already received over 450K views since the release (watch below). Why did Boyce Avenue want to hep out PoP? Lead singer Alejandro explains:

"After traveling the world touring in support of our first album we really felt like we wanted to get together with our amazing fans and give something back," he says. "'One Life' has an inspirational and aspirational message so we thought it would be a great fit for Pencils of Promise. Our mother is a teacher and we've always believed that every child should have a global right to an education so that they can realize their full potential."

PoP helps to make teacher programming and build schools. Boyce Avenue is also involved in a more music-centric collaboration, with You Generation, a partnership between YouTube and Simon Cowell's SYCO Records, for the Live Covers Competition. The challenge: making a hit song sound like an original. The winner of the Live Covers Competition will fly to Los Angeles or London to be the opening act for Boyce Avenue on their 2014 tour. (You actually may be able to enter before November 21, 2013.) And how did this collaboration come about? Boyce Avenue coached the second season of The X Factor
