In 2008, he released “Beethoven's Wig 4: Dance Along Symphonies,” another concept album in which each song featured lyrics for classical pieces written for dances and marches. In this album he expanded the reach of previous Beethoven's Wig albums by including pieces by American composers Scott Joplin and John Philip Sousa. Perlmutter co-produced the album with Michael Geiger, a bass in the Los Angeles Opera, who has also sung on three of the Beethoven's Wig albums. Beethoven's Wig 4" brought Perlmutter his fourth Grammy Nomination.
