Although not in the same vein as the deliciously hallucinogenic earlier Floyd works such as Ummagumma and Dark Side of the Moon, Animals is innovative and musically diverse in its own right. Inspired in part by George Orwell's political fable Animal Farm, Roger Waters condemns the avarice and inequalities of capitalism, metaphorically and musically grouping humans as pigs, dogs, and sheep. The pigs are self-righteous hypocrites inflicting their beliefs on everyone else, the dogs greedy money-grabbers, and the sheep witless followers. Dark, cynical, and brilliantly composed, Animals is an ingenious and under-acknowledged album. --Naomi Gesinger
