The Flower Kings!
Alright...come on. You fellas knew all about this band didn't you...and you decided you weren't going to tell Oakers?
Took my first dip with an epic double CD called Flower Power, and frankly it's awesome. Wonderful complex and varied prog' shot through with memorable melodies, riffs and musicianship. If by chance you haven't heard them before and decide to investigate, those of you who like to do the 'sounds like' thing will need a long checklist at the ready. Intentionally or not, they reference just about everybody...including Focus at the start of this monster guitar track...which is as good as any spacey guitar track I've heard in a long time. And it only too me 15 years to find it...
