Thicke played across the country in the spring to support his latest album, "The Evolution of Robin Thicke," which reached No. 5 on The Billboard 200 when it was released last year. The set has spawned the platinum-selling song "Lost Without U" as well as the latest single, "Can U Believe," which is making waves at R&B/hip-hop radio.
