There are so many greatest hits collections of the best of the Animals that at first glance "Retrospective" just seems like the latest in a long line of such albums going back to ABKCO's 1966 collection of "The Best of the Animals."  A reasonable person could be content as long as their CD has "House of the Rising Sun," "Don't Let Me Be Misunderstood," and "We've Got to Get Out of This Place."  But for fans who see the Animals as the second best English R&B group of the British Invasion after the Rolling Stones, this 22-track collection deserves prime consideration if no other reason than all of the tracks come from the ABKCO masters and utilize Direct Stream Digital (which is what ABKCO successfully used in the Rolling Stones albums reissued in 2003).  Yes, it is a pain when you get albums and then a few years later they are digitally remastered or whatever to make them sound even better than before, but maybe your dog will eat your Animals CD or you will lend it to a friend who never returns anything and you will need a new one, which will justify your picking up "Retrospective."
