Brooklyn trio the Rub have done some insanely thorough curating with their series of yearly rundowns of the best (in their learned opinions) hip-hop tracks. They've strung together dozens of gems for every year from 1979 to 1999 (you can access the MP3 files here). That is some serious dedication and edification, boom-bap aficionados.
Below are a few videos from some of my faves that the Rub have included in their pantheon.
Just-Ice's “Cold Gettin' Dumb” (1986)
Gang Starr's “Who's Gonna Take the Weight” (1990)
GZA's “Shadowboxing” (1995)
Fu-Schnickens' “Ring the Alarm” (1992)
