Okay, here is another dreamband since I couldn't put all of my favourite mussicians in one band:
Vocals: Oliver Hartman

(Hartman, Ex-Centers, Ex-At Vance) (This guy is just criminally underrated. I discovered him when I discovered At Vance. He has done backing vocals for many Power Metal bands like Rapshody, Edguy or Avantasia and after he left At Vance in 2002 he founded his own AOR band Hartman. Defenitly worth checking out!)
Guitars: Manni Schmidt

(Grave Digger, Ex Rage) (I first knew him because he played in Rage from 1987 to 1993 and played on classic albums like Perfect Man, Trapped and The Missing Link. In 1993 he was kicked because he wanted to spent more time with his family. In 2001 he joined Grave Digger and he really fits into this band more then he would fit in Rage since the band changed so much since he left it. Great guitar player)
Guitars: Olaf Lenk

(At Vance, Ex-Centers). (Also very unknown and underrated guy. He is the guitar player and mastermind behind At Vance, one of my favourite bands. You can hear that he is very much influenced my Yngwie Malmsteen, but his style of playing is less flashy, more melodic and more in the direction of power metal and not only fast and flashy for the sake of beeing fast and flashy like Yngwie on his albums. I would check him out.)
Comment: I know both Lenk and Schmidt are very different but I like the contrast of Schmidt who has a more rough speed metal style of playing and Lenk who is more the Malmsteen Neo-Classical kind of guy)
Bass: Jari Kainulainen

(Evergrey, Project Strato, Ex-Stratovarius, Ex-Warmen, Ex-Kotipelto) (I don't think I have to say much about him! He is just a great bassplayer!)
Drums: Mike Terrana

(I can't keep track on all the bands he was in. He currently plays with Masterplan, Tarja Turunen and Axel Rudi Pell. He played for Rage, Yngwie Malmsteen and even a few gigs with Gamma Ray in the past) (Okay, appart from him beeing arrogant and having a very big ego he is always funny and propably one of the best drummers out there!)
Keyboards: Jens Johansson

(Stratovarius, Ex-Dio, Ex-Yngwie Malmsteen and also gues appereances in a looooooooot of bands) (Do I really have to write anything?)
