Pete Rock (basically, everything. When you've got it, you've got it).
Marley Marl (especially his COLD CHILLIN' shit back in the late '80s/early '90s)
The RZA (a little patchy at times, but he generally holds my interest)
D.J. Premier (his drum sounds alone are enough to floor me everytime...)
Erick Sermon and Parrish Smith (the first four EPMD CDs)
Yeah, I know, I got mostly old-school choices. Sue me...
PEACE!
