LOS ANGELES — On the opening night of Silk Sonic's residency at the Park MGM in Las Vegas, Bruno Mars and Anderson .Paak revived some of the best things about the 1970s: warm, sensuous grooves, tailored polyester suits and the throwback joys of an evening without a smartphone.
As mandated by the band, audience members were made to lock their mobile devices in small pouches for the evening, courtesy of a company named Yondr. Once secured in their pouches, they could only be unlocked electronically at a station near the entrance of the venue.
"We're taking your phones a-way!" Mars sang out to the crowd near the start of the concert.
