“Today Was a Good Day.” Or maybe it’s “Dre Day?” Either way, you should probably watch a little Friday starring Ice Cube to prepare for Friday night’s hip-hop karaoke at Brooklyn Bowl. Whether you’re a fan of laying back on a smooth disco groove and dropping street knowledge, like Grand Master Flash, or taking a serious stance against police brutality like N.W.A., there’s gotta be a song for you. Are you smooth like Snoop? Dogg that is, not to be confused with his new Snoop Lion personality. Are you hard like 50 Cent? Hanging out in the candy shop? Maybe you want to get in touch with your Brooklyn roots and hypnotize the crowd with some Biggie, or make ’em shimmy with some Ol’ Dirty. Entrance is $5 with a flyer or $8 without.
