Welcome to another Boomerocity Archive Series interview...where we preserve the stories behind the music that shaped our generation.

Photographer Jeff Lowenthal witnessed Peter Green's Fleetwood Mac recording with Chicago blues legends inside Chess Studios. More than five decades later, he and historian Robert Schaffner reveal the remarkable story behind one of music's most important sessions.

Every great band has defining moments.

For Fleetwood Mac, one of those moments happened long before Rumours, before worldwide superstardom, and before the band became a household name.

On January 4, 1969, Peter Green's Fleetwood Mac entered Chicago's legendary Chess Studios—not simply to record another album, but to immerse themselves in the music that had inspired them from the very beginning.

Sharing the studio with blues giants including Willie Dixon, Buddy Guy, Otis Spann, Honeyboy Edwards, J.T. Brown, and others, the band created what many consider one of the finest British blues recordings ever made.

Few people witnessed that extraordinary day.

Jeff Lowenthal was one of them.

Armed with his camera, he documented moments that have since become invaluable pieces of music history.

Joining him is historian Robert Schaffner, whose meticulous research and storytelling helped transform those photographs into the outstanding book Fleetwood Mac in Chicago: The Legendary Chess Blues Session, January 4, 1969.

In this Boomerocity interview, Randy Patterson sits down with both men to discuss the personalities, the music, the atmosphere inside Chess Studios, and why this remarkable recording session still resonates with musicians and fans more than half a century later.

If you appreciate classic rock, authentic Chicago blues, music photography, or the preservation of musical history, you'll find this conversation both enlightening and inspiring.

This interview is part of Boomerocity's ongoing commitment to preserving the voices, stories, and cultural contributions that have shaped the Baby Boomer generation—and to passing those stories on to future generations.
