Rated 8/10
I've never been a big fan or connoiseur of funk music. So, even if I understand this is pretty good and musicians are very good, I was not terribly excited about it. In any case, the album is indeed very good (and, interestingly, not as "disco-funk" as I thought). I really enjoyed some of the songs, which, all things being said, tend to be too long.
In particular, I enjoyed the end section of "Groovallegiance" (nice guitars), "Who Says a Funk Band Can't Play Rock?", or "Promentals..." (too long though).
Interestingly, I enjoyed all three songs in the EP more than I did with any of the songs of the main album. So, I really liked "Lunchmeataphobia", "P.E. Squad...", and "Maggot Brain" (my favourite track in the whole "album").
It's in the range of 3 (without the EP) or 4 stars (if the EP is included) for me.
