The Listen Up! tour launched in late May at San Francisco's Fillmore. Fans can expect to hear new, original material from the performer's forthcoming album. A release date for the album has not been announced. 

The concert also gives fans the chance to hear songs Criss performed on "Glee" and in his Starkid shows. Material from his EP "human" will also be included.

The final tour dates follow:

June 27, New York, NY at Roseland Ballroom
June 28, Philadelphia, PA at Theatre of Living Arts
June 29, Boston, MA at The House of Blues
June 30, Silver Spring, MD at The Fillmore

Criss also wrote and starred in A Very Potter Musical and A Very Potter Sequel, based on the "Harry Potter" series. His "Glee" cover of the Katy Perry hit "Teenage Dream" debuted at #1 on the Billboard charts, a first for the series. Criss has also been seen on the television series "Eastwick," "Cold Case" and "Archer."

He made a splash with his Broadway debut in the 50th anniversary revival of How to Succeed, selling out his first performance after he took over the role of J. Pierrepont Finch for original star Daniel Radcliffe ("Harry Potter"). His three-week engagement proved to be box-office gold for producers, with increased ticket sales and several sold-out shows.

Tickets are on sale via Ticketmaster.
