Alex Preston hasn't mastered the drumstick toss, but can he sing? He auditioned with an original song on the guitar, which was more of an instrument to tap a beat on. His voice sounded very current and interesting. Jennifer Lopez couldn't believe that was an original song and could tell he was a comfortable performer based on the way he connected with each judge during his performance. Alex is going to Hollywood with three yeses, and his concerned parents couldn't be more proud.
