fair enough not being into neurosis but to suggest isis or cult of luna are less boring!? i wonder how much neurosis you have heard? isis are a bland regurgitation of neurosis at the best of times (...of grace).
plus isis veer more into post-rock and neurosis would surely be doom prog rather than prog metal?
i think the trio of vocalists in neurosis are one of the most powerful in extreme music history.
i too am regular disappointed by glam vox, the new dragonforce album would probably be appreciated a lot more by me if it wasn't for the inane and desperately unoriginal wailing over the top, sometimes instrumental is just the most reliable choice.
do mastodon count as prog metal? there are some talented growlers!
