Tobias Sammet runs 2 successful bands in parallel! He sings for 2 bands, writes music and lyrics for 2 bands, tours with 2 bands, etc. He's been doing that for 15 years!
Sometimes he plays bass.
Tobi founded Edguy when he was 14.

This type of projects also need lots of talent and versatility to write songs that fit the styles of so many different singers. Besides, Avantasia is a metal opera and the stuff is not easy.

Annihilator = Jeff Waters. He's one of the most multi-talented metal musicians. Definitely a guitar virtuoso.
He's basically a lead guitar player but his roles in the band are more than that:
Founder, leader, songwriter, lyricist, and when needed - rhythm guitar player and even bassist and lead vocalist. He founded his own studio and became a producer.
Annihilator didn't have a bassist for their debut album (which is a masterpiece) and Jeff Waters created and played all the original bass lines (besides creating everything else).

The guys from Primal Fear are very good and skillful musicians but they wouldn't sound that good without the great songs Mat Sinner writes. Primal Fear just have good songs.
Mat Sinner is also their bassist and co-founder of the band. I always compare Mat Sinner with Steve Harris - both are Grey Cardinals: they exert power behind the scenes, without drawing attention to themselves. Also both are bassists and know how to write good songs.
