Classic rock and blues band Cactus -- often called the American Led Zeppelin -- reunites for the first time in more than 30 years in this hard-driving 2006 concert filmed at B.B. King's Blues Club in New York. Original members Carmine Appice, Tim Bogert and Jim McCarty perform with new lead singer Jimmy Kunes and special guest Randy Pratt on harmonica, delivering a driving set that includes "Cactus Boogie," "Parchment Farm," "Long Tall Sally."
