I agree that Guru is underrated. Dude held it down on those Gang Starr LP's and the first three Jazzmatazz projects. I think his monotone style wasn't everyone's cup of tea though and being in a group with the GOAT doesn't help either. He was an older dude too so the youth wasn't fucking with the content with the exception of Hard to Earn. I think that album rubbed the older heads the wrong way lyrically. That was the harshest Guru ever got IMO.
