Piero F. Giunti

is a Los Angeles-based photographer, filmmaker, curator and cultural historian whose work documents music, identity and communities often overlooked by traditional cultural institutions.

The Black Eyed Peas, Dolores Huerta, Alice Bag, Jackson Browne, Bonnie Raitt, Peter Frampton, Rubén Blades, Billy Gibbons, Danny Elfman, Los Tigres del Norte, Brenton Wood, Tierra, Redbone, WAR and many others, preserving their histories through photography, film and recorded oral history.

His work has appeared in publications including Rolling Stone, Esquire, Vogue, Billboard, Variety, and the Los Angeles Times, and his photographs are held in private collections throughout the United States and beyond.

At the center of Giunti's work is a belief that communities should not have to wait for institutions to decide that their histories are worth preserving.

Mark Guerrero

is a Los Angeles-based musician, songwriter, producer, historian and cultural archivist whose life and work are deeply connected to the musical history of East Los Angeles. The son of legendary musician Lalo Guerrero, widely recognized as the “Father of Chicano Music,” Guerrero has spent decades both participating in and documenting the evolution of Chicano and Los Angeles music. He is the co-founder of A Great Day In East LA® and has been part of the project from its beginnings.

Guerrero began performing during the 1960s as the leader of Mark & the Escorts, becoming part of the generation of Eastside musicians whose bands helped define what became known as the Eastside Sound. His career has continued across decades as a recording artist, songwriter, performer and producer, giving him a firsthand perspective on the musicians, venues, record labels, neighborhoods and cultural movements that shaped generations of Los Angeles music.

As a historian and archivist, Guerrero has dedicated years to preserving and sharing the history of Chicano music and the artists who created it. His extensive knowledge, personal relationships and lived experience have been central to A Great Day In East LA®, helping locate musicians, uncover overlooked histories and build the trust necessary to document people and artifacts rarely represented within traditional institutions.

At the center of Guerrero's work is an understanding that this history is not something observed from a distance. It is a history he lived, inherited and has spent a lifetime helping preserve.
