The most recent issue of Filter magazine is crucial. It's cover story is on the massive effect that A Tribe Called Quest had on hip-hop and music in general during their hey-day.
It is impossible to overstate the contribution this group made. Theirs was hip-hop that took itself seriously as art. Their positive Afrocentrism was a breath of fresh air to what the mainstream was putting out in the rap genre. The interview with Q-Tip reveals much of what was going on in the world when they came along and how they affected what came afterwards.
This is a contribution often overlooked. As a testament to how truly important they were, there are two solid pages of quotes from figures in music who have been taken inspiration from what Tribe did, including the Beastie Boys, Janet Jackson, Pharcyde and Talib Kweli.
Even for Filter, this article goes above and beyond.
