Eoghan Heaslip is a great worship musician who hardly anyone has heard of. I figure that's true, because every time I ask someone if they've heard of him, they say no. But you worship leader types may be familiar with him.
He's had some notice initially, I think, because his dad is the road pastor for U2.
But whatever that info does for your impression, know that Eoghan (pronounced "Owen") Heaslip makes great worship music.
Go to iTunes and check out "King of the Ages." Great song.
