I was thinking about solos just the other day. I'm planning to make an MP3 CD full of nothing but my favorite parts of songs - solos, outtros, etc. (all bands, not just Opeth)
In all honesty, Opeth is the one band I've never really listened to in regards to picking out solos. There is something about their music that makes me listen as a complete package. There are so many parts of Opeth's music that gives me chills - the bridge before the Deliverance outtro, the Ghost of Perdition bridge at around 5:30 (I think), etc. I don't hear solos in Opeth's music. It's as if they purposefully never wanted to actually accentuate a solo like so many other bands do. My favorite guitar solos by Grip Inc, Enslaved and others seem to be set-up. The "solos" in Opeth's music flow and never seem set-up to me, therefore, I never really hear them as solos.
Does my babbling make any sense?
