I'd go for "Scoundrel days", then "Analogue", two of their best in my opinion.
As for Gazpacho, love them! Have you got the new album (soon to be reviewed in my journal)? I loved "Missa Atropos", and have the rest of their discog to get through, but I'll be giving "The march of ghosts" a spin first!
But unsigned? Aren't they with KScope now?
