Boyce Avenue

They are a Rock band from America who have been warm up acts for The Goo Goo Dolls, One Direction and Switchfoot. They mainly do covers which are, in my opinion, sometimes better than the originals. All their covers are available on both iTunes and YouTube. They have two albums of all their own songs named 'All We Have Left' and 'All You're Meant To Be' which are as amazing as some of their covers. Their mash up of 'Iris' and their song 'Broken Angel' is probably my favourite. 

There are three members: Alejandro Manzano, Fabian Manzano and Daniel Manzano.
