Evaluating an Animal Collective album is a daunting task.  Whereas a couple of spins of most artists’ records will give you a good sense of their charms, hearing any of Animal Collective’s work just a few times is barely scratching the surface.  If first impressions hold true, however, the journey on which fans are about to embark with the band’s latest full length, Centipede Hz, stands to be as rewarding as any Animal Collective has sent them on before.
