Plain and simple friend, kicks the living shit out of GR.
It's just a classic. There isnt a single song on that album that I cant say that I wasnt impressed with. Songs like the Moor, Godheads Lament and Serenity Painted Death alone eat anything on Ghost Reveries alive.
Overall, the sound on SL is just so much warmer, and more pleasent then on GR, and the album flows from song to song a whole lot more smoothly. A lot of people are big on the whole concept behind this album, but regardless, this is one beautiful fucking album.
(sort of an unrelated edit here - I notice that your into MDB Sadpoet, they're one of my favorite bands. What's your favorite album... if you say 34.788% complete, someones gonna get hurt)
