Dan Farrell, program coordinator of the Phantom Regiment, elaborated on the corps' 2004 program, titled, "Apasionada 874 -- The Music of Astor Piazzolla." "It's a little different than what we've done in the past," Farrell said of the Argentinean composer's work. "The music is pretty unique, as far as its background and instrumentation. It's not traditional classical music that we've done in the past. It's breaking away from those traditional roots that we've clung to." According to rootsworld.com, a "Network of culture, art and music on the web," the music of Astor Piazzolla "epitomized our situation in the modern world with his fusion of folkloric beauty and contemporary tension. He forged a new music that challenged the traditionalist and left the adventurous craving more. He took the music of the great tango masters like Garde, ripped it away from the velvet-walled concert hall and the soft-cushion drawing room, and slapped it down on the pavement of Buenos Aires. Reviled by the critics, shunned even by the conservative government, his music spoke to the next generation, and popular and jazz musicians and listeners all over the world eventually fell under the spell of his "nuevo tango."

Selections of the Phantom Regiment program will include "Buenos Aires Hora Cero," "La Muerte del Angel," "Oblivion," "Imagenes 676," "Adios Nonino" and "Tres Minutos con la Realidad."
