Yesterday I played Porcelain in 1-Step down, in Open Dm ( like ghost of perdition) and in Drop D.
Mikael should play it in Drop D or Open Dm but we hear that he let ring this part;
In Open Dm;
that's easier to let ring 3rd string here...
D-----------------------------------------------------|

And also ve hear him sliding on the clip...
But in Dropped D

Doing
D-3
A-7
D-3
and letting it ring is harder than the other one. I dunno if Mikael can do it but I can't

so i prefer Open Dm for playing it...
