Manilla Road headlining
Elixir
Trouble
Candlemass
Angel Witch

All these bands have a strong individual identity and are just ... GREAT!

Hmmm, I don't know anything about Keep It True Festival, but if I lived near by, I'd love to see a lot of bands I've never been able to see, such as;

Manilla Road
Candlemass
Solitude Aeturnus
Mercyful Fate
Ancient Rites
Grave Digger
Gamma Ray
Iron Savior
New Eden
Nocturnal Rites
Memento Mori
Memory Garden
Doomsword
Star One/Ayreon
Steel Prophet
Redemption
Agent Steel
Narnia
Zero Hour
Labyrinth
Sadus
Royal Hunt
Revelation
Onward
Falconer
Imagika
Galloglass

I'd better stop there, but the list doesn't take into account bands I've already seen and would like to see again or bands that are disbanded or can't tour.
