Even now, as he reaches his eighth decade, with a lifetime of accolades and a seminal body of music behind him, Robin Trower is still chasing the biggest high he knows.

It always starts the same way, with a road-scuffed Fender Stratocaster and a revved-up Marshall amplifier, those skillful fingers exploring the fretboard until a riff sticks and a new song ignites.

And from the cultural flashpoint of ’60s London with Procol Harum, through 1974’s stadium-filling “Bridge Of Sighs,” right up to this year’s acclaimed “Come And Find Me,” it’s these addictive moments of creation that have kept the guitarist vital, relevant and contemporary while his peers trade on past glories.

“Some people say I’m driven, but I think it’s just the love of doing it,” reflected Trower of a multimillion-selling solo catalog fast approaching 30 releases (and that’s before you compute his collaborations with everyone from Jack Bruce to Bryan Ferry).

“I play guitar every day and just through messing around, ideas happen,” he said. “I can never feel the songs coming. But all of a sudden, you get a sliver of an idea and you think, ‘Oh, what’s this?’ …”

This latest tour represents a mere stretch of the long road traveled for Trower. In his mind’s eye, Trower can still see his Southend-on-Sea childhood in the ’50s, and feel the formative influence of guitar players from across the water.

The big time beckoned in 1967 when Trower joined “A Whiter Shade Of Pale” hitmakers Procol Harum, and many guitarists would have clung to that enviable position for life.

Trower acknowledges his good fortune at being at the epicenter of that late 1960s youthquake (“I still think it was the epitome of U.K. popular music and rock ‘n’ roll”). But Procol’s band dynamic could never contain all his ideas, and after five acclaimed albums, Trower rolled the dice on a solo career.

“It was something I had to do,” he told Classic Rock. “But it could have all gone awry.”

Needless to say, the history books have vindicated him. By 1974, Trower was a major star in the land whose music had inspired him, with “Bridge Of Sighs” heavy soul achieving Gold U.S. sales and influencing future luminaries like Steve Lukather, Metallica and countless more.

Yet the veteran doesn’t dine out on “Bridge Of Sighs” — or his other hit albums of the late 1970s like “For Earth Below,” “Long Misty Days” and “In City Dreams” — preferring to march ever onward.

Stick a pin in his catalog over the past decade alone and you’ll find projects from 2020’s “United State Of Mind” supergroup alongside Maxi Priest to the pairing with New York vocalist Sari Schorr on 2023’s “Joyful Sky.”

“She’s dynamite,” he says of the latter, “and ‘I’ll Be Moving On’ is a particular favorite of mine from that album.”
