Starting the year playing some of my favorite band Opeth!
Ghost of perdition is the opening track from their 2005 album Ghost Reveries. I played this instrumental for now, hoping my good friend 
Also only played the intro part, as this song is 10 min long. I know i should stop being so lazy and play the whole thing, most of my favorite songs are that long or longer...
On bass you can enjoy from the amazing Bora Leo Duzey, known as Leo Bass Covers on youtube.
Enjoy!
