West coast has always had some good indie hip-hop acts like Freestyle Fellowship, The Living Legends (from which Slug of Atmosphere and Murs repped, also including the Grouch), Mystik Journeymen, Hieroglyphics, The Shapeshifters, People Under The Stairs, LA Symphony, Blackalicious, Jurassic 5 etc...Only cacs were bigging up that garbage. I tuned out of the underground when it became saturated with nerds raping about raping
But that was more of the east coast underground. The west had groups that were still decent and underground like dilated peoples, madlib and slum village in the Midwest and their whole sound and affiliates. Little brother etc. These were dope indie acts that followed in the roots of the good parts of the underground movement that preceded from cats like Mos def and Talib, pharoahe... The other side of it was shyt like company flow, Aesop rock etc was utter trash to me.
I discovered this from a skate video back in the day, might of been Bluetorch TV or Logic Video Mag
