In September 2009, Maroulis launched his "A Night at the Rock Show" series of sold-out solo shows in New York City, featuring "Constantine's unique interpretations of some of the greatest rock songs of all time," and backed by an all-star band. Maroulis returned to the Idol stage to perform on April 7, 2011, where he debuted his single, "Unchained Melody". At the same time he also released his rendition of Chicago's 25 or 6 to 4, as recorded live at a Night at the Rock Show performance.

In conjunction with this project, Maroulis released a new single, an updated version of the Kinks' classic "You Really Got Me". Maroulis partnered with the New York-based 1980s tribute band Jessie's Girl and frequently performed with them at various concerts and private events.
