I think the main reason I love Hypocrisy is that they excel in slow, mid, and fast tempo songs. A Coming Race is my favorite.
Look at the masterful Apocalypse and The 4th Dimension, very slow, but not grind Morbid Angel or Crowbar slow. Hypocrisy can just do sloooowwwwww songs that are still intense. Then there's slow-mellow like Slippin' Away. Those guys do it all, sheer genius. I've been listening to death metal for about a decade now and no group has completely blown me away the same way Hypocrisy does.
