found these guys (girls I guess) by accident after listening to the original Rihanna Love the way you lie part 2 on You Tube.
a really talented duo who are really good at taking a pop tune and doing a refreshingly sympathetic and different acoustic rendition always with great melodies and harmonies.
you should check out their other covers - I'm totally hooked on their stuff since I found them - RUDE BOY is another excellent cover.
their own stuff is not bad either - more pop and not acoustic.
if these folks don't "make it" in the pop arena - which I wish them all the best with - then I hope they continue to do covers as it takes a different sort of skill to do this well - to retain the appeal of the original track whilst giving it a new arrangement and adding a twist of something a bit different.
their Bruno Mars cover is recommended too.
