Lot's going on here. There's a fusion of a bunch of different styles on this like funk, soul, maybe some rock and reggae. Generally, these are styles that encourage loose, free form playing. However, this is a tight album with boatloads of discipline and measurement in this music. Boatloads of discipline is good, but boatloads of weed is better. And that's what it'll take to get these guys to relax a little. Actually, listening to this makes me need a boatload of weed to relax a little. In any case, it's evident these guys like playing music together and have put in a lot of time. The sound, even if it were less constrained, isn't my jam, but some people (like government employees and tax collectors) might enjoy this album's strict recipe for creating music.
