In class we continued listening to Zepp IV and while it was entertaining watching people argue over the volume, the album got slow more than a couple of times and yes, I know some of the songs are really long but it got slow in terms of lack of action in certain spots though they also had their moments of good old loud rock and slower songs (more notably Stairway to Heaven) that despite clocking in at about 8 minutes (bested in length by GN'R's November Rain and Coma) changes throughout and introduces different sounds.
