This year’s Super Bowl halftime show was not so much a celebration of hiphop than a celebration of one of its brightest and most talented stars, Dr. Dre, who is now a billionaire. He sold his ownership of Beats earphones to Apple; he discovered Snoop, Eminem, and 50 Cent, all of whom participated at the halftime show. But here is the thing. After Dre left NWA in the early 1990s, he began a creative journey in hiphop that can only be described as remarkable. He made hit after hit. And each of these hits (“Nuthin’ but a “G” Thang,” “Still DRE,” “Keep Their Heads Ringin,’” and so on) is in the cannon. Dre has also thrown his bright light on mid-career Kendrick Lamar, who provided the most electric performance last Sunday. Dre deserves every ounce of respect we can give him, which is why it’s appropriate that the Royal Room is celebrating his 57th birthday on Saturday, February 19. It’s Dre day, with great local hiphop producer Vitamin D leading a live band.
