Putting together this show and album affected me in a deep and profound way quot; Spector notes. The 2014 album which features music from artists like Billy Joel Enrico Caruso Little Richard Freddie Mercury Stevie Wonder Paul McCartney and Bono required exhaustive research. quot;In researching this album I was immersed in the music of these venerated artists whom I ve adored my whole life. After portraying one man [Frankie Vallie] for 1500 performances with Jersey Boys I was haunted by identity fears. Being able to delve into the repertoire of other artists helped quell them. I now feel a sense of fraternity with these artists.
