Of course in that last video, vocal effect-wise, Obscura were channeling a bit of Cynic. Which isn't very surprising, really.
The wife and I saw Obscura opening for the Death tour a couple of years back. And of course most of the members of the Death To All tour, a sort-of reunion (without Chuck, of course) were also in Cynic. Obscura themselves covered Death on one of their first album releases.
A private instance for the Finkhäuser family.
