T-Rock’s wild rhythms mix Gypsy (Roma) jazz of the Django Reinhardt-Stephane Grappelli class with Rock (a la Jethro Tull), Celtic, Psychedelic and Italian tarantella folk roots. It’s an intoxicating and fresh combination of sounds, the band incorporates minor-key accordion and a special violin with distortion and guitar effects. In a typical concert, T-Rock dishes out irresistible dance rhythms from such Italian roots as Saltarello, Pizzica, and Tarantella (to say nothing of a creative reworking of “Funiculi Funicula,” well-known even to Grateful Dead fans), in addition to ska, Celtic, and Latin influences, all performed with a Very Rock aplomb.
