Voice of the city: Vegas native Mr. Bob found his space on the air

One of Las Vegas’ all-time most popular radio voices just happens to be a born-and-raised native—Robert Alexander. You know him as Mr. Bob, keeping the hip-hop party going six nights a week on Hot 97.5 FM and hosting Global Saturdays at Embassy Nightclub.

“I grew up on the west side,” Bob says. “My dad came home one day and told my mom there’s a new development called Green Valley and he wanted to find a house out there. It was a lot different—in a week I went from ‘Yo man, what’s up’ to ‘Yo dude!’

After graduating from Green Valley High and taking a stab at junior college football in San Bernardino, Bob got his real break while working at Costco.

“One day this dude comes in, bald head, hoop earrings, bomber jacket, Timberlands, looking very East Coast,” Bob says. “What’s this guy’s story? He asks if I ever listen to 91.5. Then he says, ‘I’m Warren Peace.’ I got a total high pitched voice, like, ‘Oh my God! I listen to you every Friday!’”

Peace took Bob under his wing, gave him his nickname (“I thought ‘Mr. Bob’ was so corny at first.”) and put him on air and onstage as his hype man. When 98.5 KLUC-FM grabbed their Friday night mix show from the college station, Bob really found his own voice, learning the radio ropes and letting his outgoing personality shine. “I’d sit in on everyone’s shows to see how they ran the board. I sucked it all up like a sponge, then put my own spin on it. It was a dream to be on the station I grew up listening to.”

Now at Hot 97.5 for the last seven years, Bob has had a No. 1 show on all three local stations where he’s been on the air. He’s one Vegas native who has truly found his calling.
