"Yahoo! On the Road will be traveling across the country and stopping along the way for a summer concert series, (check out the schedule here). You may know all the words to songs by some of the artists who will be performing, like Skylar Grey and Macklemore, but do you know their real names? Test your knowledge for these musicians and more, and be sure to head over to Yahoo! On the Road's Flickr page for more photos. -- Tiara Chiaramonte, Yahoo!
