Born to Greek-American parents in 1975, vocalist Constantine Maroulis grew up listening to a wide range of music in his suburban New Jersey home, with particular favorites ranging from Frank Sinatra to Guns N' Roses. Inspired by older brother Athan's success as a singer, publicist, and label owner, Constantine began taking steps to launch his own entertainment career. He enrolled in the Boston Conservatory of Music in 1999 and received his degree in musical theater three years later. He then found an apprenticeship at the Williamstown Theater Company, through which he gained the attention of the director for the international production of Rent. The director later cast Constantine in the part of Roger, during which time he was also singing lead for the band Pray for the Soul of Betty. The intersection of theater and rock music proved to be a happy home for Constantine, who would later make high-profile forays into each arena.
