The lead singer on Paradox Voice Band’s new mash-up, “Shut Up and Dance with Somebody,” Tenor-Beatboxer Tom Ostrander has been singing since he could talk, beginning with reciting songs from such classic Disney films as “Pocahontas,” “The Aristocats,” and “Snow White and the Seven Dwarfs.” Growing up in a musical family, Tom was exposed to a wide variety of musical genres, from the classic pop-rock of Billy Joel to soundtracks from musicals like “Les Misérables” and “Pippin.”
