After rockin' the rafters of the Resch Center last week with Y100 it was off to Country Radio Seminar Week in Nashville and, the 'New Faces Show' , the Grand Finale to the week of artist interaction with Country Radio. Florida Georgia Line was the main attraction at this year's show as they wrapped up the night with a record breaking debut number 1 song from a new Country Duo. First time that's happed since 1991 with Brooks and Dunn arriving on the scene with "Brand New Man." To celebrate Florida-Georgia Line's success, a surprise Superstar labelmate joined them on stage to help singing , "Cruise." Can you see who it is?
