Singer-songwriter duo A Great Big World -- comprised of the supremely talented Chad Vaccarino and Ian Axel-- are making some serious waves. They've ended up on Christina Aguilera's radar and that's just the tip of the pop music iceberg, as they're nabbing fans left and right with their amazing compositions.

That's what made A Great Big World ripe to participate in our 10 Things You Didn't Know feature. Here, you can learn which member managed the other before they decided to go the team route; whose hair changed texture when he began singing; what their go-to place is while on the road; and much, much more.
