This is an unreleased song that's on their upcoming album of rarities. I only figured out the first riff. 6 beats in one riff e|-----------------------------| B|------------0----------------| G|----------10---------------0-| D|-9h12---10--------11-----10--| A|------10--------10--10h11----| E|-----------------------------| e|-----------------------------| B|------------0----------------| G|----------10---------------0-| D|-9h12---10--------11-----10--| A|------10--------10--10h11----| E|-----------------------------| e|-----------------------------| B|------------0----------------| G|----------10---------------0-| D|-9h12---10--------11-----10--| A|------10--------10--10h11----| E|-----------------------------| e|-----------------------------| B|------------0----------------| G|----------10---------------0-| D|-9h12---10--------11-----10--| A|------10--------10--10h11----| E|-----------------------------| e|-----------------------------| B|------------0----------------| G|----------10---------------0-| D|-9h12---10--------11-----10--| A|------10--------10--10h11----| E|-----------------------------| e|-----------------------------| B|------------0----------------| G|----------10---------------0-| D|-9h12---10--------11-----10--| A|------10--------10--10h11----| E|-----------------------------| e|-----------------------------| B|------------0----------------| G|----------10---------------0-| D|-9h12---10--------11-----10--| A|------10--------10--10h11----| E|-----------------------------| e|-----------------------------| B|------------0----------------| G|----------10---------------0-| D|-9h12---10--------11-----10--| A|------10--------10--10h11----| E|-----------------------------| Only the intro.
