Glee star Darren Criss is heading out on his first solo tour as he gears up to unveil his debut album. The singer/actor is kicking off his 16-date Listen Up trek on 29 May (13), in San Francisco, California, and he's promised to preview a handful of new tracks at each of his concerts. A statement from the star reads, "I couldn't think of a better way to spend the summer than being on the road and doing live shows. I wanted to do something bigger than what I've done before - more cities and new music. It's a real opportunity for me to connect with all the people who've supported me through the years, as well as a chance to get new folks excited. It's gonna be a party for everyone!" In 2010, Criss released a digital EP, Human, which peaked at number 17 on Billboard's Top Heatseekers chart in the U.S.
