Sebbo has 2 Concept Insomnia concerts.

Founded in 2004 Concept Insomnia stands out for a type Progressive Metal which hasn’t been played by german Metalbands ever before! Expressive vocals and shattering growls combined with atmospheric keyboards meet mutable guitars and a precise rhythm section. There’s no doubt about it…Concept Insomnia perfectly manage to build a bridge between filigree melodies and a pounding brutality.
