I voted for the double concept album, but that's only because I would love to get 2 CD's worth of music from the guys in 1 shot. However, to be realistic I would love them to do another concept album. I think "V" was an absolute masterpiece and would love to see their interpretation of another cool story. Actually, I think it would be cool if they developed their own story this time. That would be a progression for them in terms of writing music. Hell, if King Diamond can do it time after time, then SyX can do it and far better!
Come on guys, give us a long (full CD) concept album based on an "original concept" with a wide range of styles and moods and at least one 15 minute long song (ala "Rediscovery I & II).
