In Brief:

*** 1/2 Digital Underground, “This Is An EP Release,” Tommy Boy. This rap group’s blend of funk ‘n’ frivolity--racy without being raunchy--reaches a new high on this EP. Just about everything is a highlight, from “Tie the Knot,” an amusing sendup of weddings, to “Arguin’ About the Funk,” a comical bickering session that’s really an astute appreciation of funk’s roots. Albums are rated on a scale of one star (poor) to five stars (a classic.)
