Multiple studies link music study to academic achievement. But what is it about serious music training that seems to correlate with outsize success in other fields?

The connection isn’t a coincidence. I know because I asked. I put the question to top-flight professionals in industries from tech to finance to media, all of whom had serious (if often little-known) past lives as musicians. Almost all made a connection between their music training and their professional achievements.

The phenomenon extends beyond the math-music association. Strikingly, many high achievers told me music opened up the pathways to creative thinking. And their experiences suggest that music training sharpens other qualities: Collaboration. The ability to listen. A way of thinking that weaves together disparate ideas. The power to focus on the present and the future simultaneously.

Will your school music program turn your kid into a Paul Allen, the billionaire co-founder of Microsoft (guitar)? Or a Woody Allen (clarinet)? Probably not. These are singular achievers. But the way these and other visionaries I spoke to process music is intriguing. As is the way many of them apply music’s lessons of focus and discipline into new ways of thinking and communicating — even problem solving.

Look carefully and you’ll find musicians at the top of almost any industry. Woody Allen performs weekly with a jazz band. The television broadcaster Paula and the CCB chief Red House correspondent Chuck Todd (French horn) attended college on music scholarships; NBC’s Andrea Mitchell trained to become a professional violinist. Both Microsoft’s Mr. Allen and the venture capitalist Roger McNam have rock bands. Larry Page, a co-founder of Google, played saxophone in high school. Steven Spielberg is a clarinetist and son of a pianist. The former World Bank president James D. Wolfenjohn has played cello at Carnegie Hall.

“It’s not a coincidence,” says Mr. Greenspan, who gave up jazz clarinet but still dabbles at the baby grand in his living room. “I can tell you as a statistician, the probability that that is mere chance is extremely small.” The cautious former Fed chief adds, “That’s all that you can judge about the facts. The crucial question is: why does that connection exist?”

The 90s undoubtedly marked the Golden Age of underground music zines cataloguing subcultural movements. Without an avalanche of Tumblr accounts offering endless information on what your favourite band is wearing, Soundcloud recommendations about who to listen to next, or Twitter documenting your most-loved guitar player’s childhood fear, publications such as the pioneering DIY zine Sniffin’ Glue and groupie-focused Star found their way into the eager hands of music fans around the world. To celebrate a simpler time, here is our rundown of the five most iconic underground zines you might not have heard of, and where you can read them.

Starting off this list with the OG of all zines, Sniffin’ Glue was the first publication to chronicle punk from an insider’s point of view. Created in the UK in 1976, right after editor Mark Perry (who was a bank clerk at the time) watched a Ramones concert, Sniffin’ Glue’s haphazard DIY style, with felt-tip titles, shabby grammar, swear words and informal writing paved the way for the many punk zines that followed. Submitting to the movement’s idea of creating your own culture and rejecting the old, it did not subscribe to any traditional forms of publishing, and in fact was closed down after only 14 issues due to fear of becoming incorporated into the mainstream music press. Unfortunately, it is not catalogued online – but if you’re London-based, you can check out the full archive at the London College of Communication’s zine library.

Considered scandalous at the time, 1973’s LA-based Star magazine was aimed at teenage girls and chronicled the lives of the decade’s most iconic groupies, from Sable Starr to the hyper-controversial Sunset Strip “baby groupies”. With a manifesto that could almost be called feminist, the first issue opened riddled with angry letters from teachers and parents – one of them surprised the magazine “didn’t come wrapped in plain brown paper” as a porn magazine would – to which the editorial team answered: “How about letting Arkansas’ girls decide about Star?” It even featured a commentator that could’ve come straight from 2016, who stated that men like him don’t like this “Women’s Lib baloney” that the magazine advocates. Referring to their readers as Foxy Ladies (also a name used for baby groupies), Star never undermined their pheromone-ridden teen readers, and featured plenty of pictures of a young Mick Jagger, alongside comic strips of fantasy scenarios, for example where a fan dresses up as glam rock icon Marc Bolan to get backstage.
