Bruno Mars and Anderson .Paak have a new collaborative project called Silk Sonic. Bootsy Collins presided over their debut album, and its lead single “Leave The Door Open” is projected to debut close to the top of the Hot 100 next week (though all those new Drake songs will probably stop it from entering the chart at #1). In recent days, Mars has been waging a social media campaign petitioning the Grammys to let Silk Sonic perform on this Sunday’s telecast. And in less than shocking news, the Grammys have agreed to let them play.
