When Ricky Riccardi was growing up in Toms Rivers, N.J., in the ’90s, most kids his age were digging George Michael or A Tribe Called Quest. Riccardi, meanwhile, was into classic Motown and vintage movies from Hollywood’s golden era. At the age of 15, he discovered Louis Armstrong.

Riccardi became mesmerized and slightly obsessed. He devoured everything he could get his hands on about the famed New Orleans jazz musician. He went on to earn a master’s degree in jazz history and became the director of research collections at the Louis Armstrong House Museum in New York, the home where Satchmo spent his final years. Riccardi also teaches a graduate course on the celebrated trumpeter, and he’s the author of Heart Full of Rhythm: The Big Band Years of Louis Armstrong and What a Wonderful World: What a Wonderful World: The Magic of Louis Armstrong’s Later Years.

This past Sunday, Riccardi won a Grammy Award for best album notes for his work on The Complete Louis Armstrong Columbia and RCA Victor Studio Sessions 1946-1966, a seven-CD boxed set released by Mosaic Records that includes more than three hours of bonus material, including unissued takes, rehearsals and even studio discussions.

“I learned everything I know about jazz from liner notes,” Riccardi said in his acceptance speech. “The music of Louis Armstrong changed my life, and that’s the crux of this box set.”

Right before the Grammys, Riccardi joined us for a conversation.
