Luke Bryan is fighting a cold on this usually stormy day in Los Angeles, but you certainly wouldn't know it by hearing him sing. The country star has done a lot of growing between his first and second albums -- not only in sales, recognition and fan base, but also in sound, as he pushes his vocals to new heights on songs like 'Do I,' 'Rain Is a Good Thing' and his countrified version of One Republic's 'Apologize,' all songs from his critically-acclaimed sophomore album, 'Doin' My Thing.'
Luke performed two of those new songs, along with two old favorites, in our AOL Music Sessions studio, nailing each performance like an old pro. And he had a little help from some famous friends. Lady Antebellum just happened to be in our studio for their own Sessions taping, so the trio stuck around to harmonize on Luke's first No. 1 song, which he co-wrote with Lady A's Dave Haywood and Charles Kelley, 'Do I.' We caught up with Luke after this rare treat of a collaboration.
