Local 7's sound and style is one that is rooted primarily in the tonality and constructs of progressive rock which sometimes can seem like a path too well traveled. But, fortunately for the listener, Local 7 breathes new life into prog rock with their strictly instrumental (thankfully), intensive, melodic themes, constantly shifting development, and unpredictable directional changes. In fact, as far as prog rock goes, this is one of the better efforts that I have heard in recent years. Andrieu does not repeat his ideas in any trite fashion, but instead is always searching for variations on his themes, as well as for new themes and directional inversions. The skill that he has in crafting his musical ideas with his technicianry produces a result that most musicians should appreciate. I especially like his attention to thematic development and his invention of savory, digest! ible themes. This is a rare talent which escapes many good musicians.

On the scale of "into it" I rate this one a thumbs up for Local 7's Substrat. This CD provides what a lot of prog rock is lacking and has driven hords of listeners to the camps of jazz fusion to satisfy more complex musical tastes. So, I would not only recommend this one to fans of prog rock, but also to fans of jazz fusion who might be interested in advanced composition, non-repetitive arrangements, and quality guitar work without the emphasis on tonal exploration and outside harmonization of abstract jazz.
