Also throw in:
Salmonella Dub
Six60
Rhombus
The Black Seeds
Ozomatli
The Cat Empire
Trinity Roots
Kukan Dub Lagan
Transglobal Underground
Some of these do sound a lot different to FFD but work on the same principle of fusing many genres together whilst still maintaining a groove as opposed to sounding like bands that lack cohesion.
Salmonella Dub's Heal Me and Rhombus's Bass Player albums are definitely recommended as being similar to FFD.
