What kind of music do fans of Heroes of Might and Magic like? (music genres)

So, yesterday I bought tickets to a concert by some band. I really liked it – this band truly plays a great example of alternative music. And immediately, a third question about the Megadeth band arose.

1) The founder of the Megadeth band played in this very band before it was formed.
2) What two cover versions of songs by famous British bands did the Megadeth band perform?
3) The lead singer of which band appears in the music video for the song A tout le monde.
Good luck. The prize is a t-shirt from the Epidemia band (size small).

Executor in Ace correctly answered 2 questions. He is entitled to a wristband with the Epidemia band's logo. And, according to unconfirmed reports, there are already three of us going to celebrate the victory of metal. The correct answers:

1) Metallica
2) Black Sabbath - Paranoid and Sex Pistols - Anarchy in UK
3) Lacuna Coil - an Italian alternative band - lead singer Cristina Scabbia (a girl of indescribable beauty). That's it.

Tomorrow is the Falling Hammer contest. Hammerfall, that is.
