Kurt Cobain's former lady Courtney Love may have had 99 Problems during this year's Sundance Film Fest…
But covering Jay-Z's iconic tune was NOT one of them!
In fact, we're kinda diggin' Courtney's hard-rocking take on a rap classic (above)!
The former Hole frontwoman performed the track at Star Bar, where rumor has it celebs like Daniel Radcliffe and Justin Bieber's manager Scooter Braun were chillaxing in the crowd.
Nice to hear Courtney strumming on her ol'
banjo guitar once again!
