Montgomery County wants concert promoter Live Nation to rock downtown Silver Spring 70 nights a year. No problem, says the company’s local guy in charge.

“It’s my anticipation to book as many nights as possible,” Ted Mankin, Live Nation’s Washington-area vice president, recently told local bloggers. In fact, he said it was a matter of survival.

“If I booked only 70 gigs a year, I’d be out of business,” he said over hummus dip at The Quarry House in late March.

According to the 30-year industry vet, profitability in the concert-promotion business depends on volume — and not the kind that ruptures eardrums. “You have to draw a steady volume of people,” Mankin explained.

For example, a well-known act would have no problem drawing crowds to the future Colesville Road venue. And it’s the big-name performer — not the concert promoter — who dictates the ticket price, Mankin said.

At Virginia’s Birchmere nightclub, prog rockers Asia and the folk duo America are hitting up fans for $60 per ticket. And at The District’s 9:30 Club, post-punksters Joe Jackson and Crowded House are asking for $40 and $45, respectively, per ticket. Meanwhile, at Live Nation’s Ram’s Head Live in Baltimore, a James Brown tribute featuring Bootsy Collins and Public Enemy’s Chuck D is going for $40 to $45 per ticket.

At those prices, a venue would have no problem turning a buck, Mankin explained.

But local and lesser-known artists draw smaller crowds and can’t demand big money from their audiences or concert promoters, Mankin added. Translation: smaller revenues to cover the same overhead costs.

“If Sara Bareilles was to come through, I couldn’t ask for more than $10 a ticket,” he said.

That’s where volume comes in. Venues will add performances during slow months to cover existing expenses, even if that means closing the balcony section or hosting a DJ night, Mankin explained.

“You can’t base [profitability] on ticket prices,” he said. “We’re going to have to be aggressive to make it work.”
