Eclipse
Serious Black
Anything with Michael Kiske.
Edit: Apparently I've subconsciously given up on Glenn ever booking Within Temptation since it didn't occur to me to list them... WT is still at the top of my wish list.
They were originally in my 3, but I altered it because my list was too djenty, lol. Plus I think, hope really hard, that they have a shot for next year.
