'Presence' is pretty much Zeppelin's prog album, or at least it's the closest they got to the genre, with expanded song lengths, tricky time signatures and some prog-worthy themes. 'Achilles Last Stand' is one of the longest songs in their studio catalog, clocking in at more than 10 minutes. But it never feels like it. Featuring one of John Bonham's greatest drum tracks, and a dozen overdubbed guitars that maximize the song's overall heaviness, 'Achilles Last Stand' stands as one of the band's most powerful cuts. You can practically feel the density of this one as it rattles every single bone in your body.
