Getting arms aloft in arenas while singing God's praises is the noble mission of for KING & COUNTRY. Talented siblings Joel and Luke Smallbone announced themselves in dramatic fashion with 2011's “Busted Heart (Hold On To Me),” a sternum-rattling plea for grace set to a thumping rhythm and harmonies that split the stratosphere.
