Which rock/metal band do you think has made the best comeback?

Metallica.

To anyone who says Megadeth, their last 2 albums before Endgame (The System Has Failed and United Abominations) were great speed-metal/thrash albums. Maybe they aren't Peace Sells or Rust in Peace but neither is Endgame. Personally I don't think Megadeth ever really went away.

Testament's Chuck Billy (vocals) had cancer and couldn't go on singing like he used to. So what does Testament do? Wait for Chuck to get better then re-record some of their classics with his new vocal style (First Strike Still Deadly) and then followed it up with the awesome The Formation of Damnation. Yes it was 7 years between those 2 albums, but what a comeback!

Alice In Chains

Alice In Chains

Asphyx - Death the Brutal Way. A great comeback. Enough to make me forget about the god awful Pestilence one.

Alice In Chains-

They really made my jaw drop

even after 14years in hiatus and losing their lead singer Layne Stanley

they made a record that stood out of the rest of the albums that were released this year,Black Gives Way To Blue is an instant classic.

And new singer William Duvall is doing an awesome job.

Hope they maintain their dominance.

STAR FOR YOU!!!!!!

Journey

after a few failed vocalist the guy they have now can sing and deen castronovo is the best drummer they have ever had

ACDC, their last album was better than their older stuff.

Shoot, i just looked at everyone else's answers and i would defintely go with Alice In Chains. They really did come back.

Alice In Chains hands down. Their new album is fantastic!

It's a tie between Megadeth and Machine Head.
