Harry A. Blazer grew up in Cranston, Rhode Island. His involvement in music began at the age of five and he took up the drums at age eight. Harry's teachers recognized his talent as a musician early on. At the age of twelve, upon the recommendation of Max Roach, Harry's mother sought out Alan Dawson at the Berklee School of Music in Boston (now the Berklee College of Music), who agreed to accept Harry as his youngest student ever. Harry would study with Alan Dawson privately for three years and become one of his most accomplished students. By age 13, Harry turned professional, and began playing with local bands of all kinds. Eventually, Harry would move to Las Vegas and later Los Angeles and play all over the world with many prominent performing artists such as Johnny Mathis, Diana Ross, Doc Severinsen, Paul Anka, Michel LeGrand, Gary Burton, Freddie Hubbard, Lee Ritenour, and many others. It was during his late teens and early twenties that Mr. Blazer met and began playing with Abraham Laboriel, Ron Feuer and Ernie Watts, forming a unique friendship with all three musicians that continues to today.

In 1979, Harry Blazer became disenchanted with the music business and in response to the needs of his brother, decided to pursue a career in the grocery industry. After spending years learning the industry, Harry took on the challenge of starting a unique food business of his own in Atlanta, Georgia. The products of his energetic efforts were the nationally recognized Harry's Farmers Markets and Harry's In A Hurry, which started with a single fresh megastore in 1988 in Alpharetta, Georgia. Eventually, his business went public and grew to three mega stores and six Harry's in a Hurry stores serving millions of customers, with 1,200 employees and revenues of 140 million dollars. In October of 2001, Harry's Farmers Market, Inc. was sold to Whole Foods Inc., the largest natural foods retailer in the country.

Throughout his twenty years as an entrepreneur, Harry Blazer never lost his love of music. In 1995, he asked his old friend Ron Feuer to play at Harry's Farmers Market during the holidays. Ron agreed, with the stipulation that Harry would play drums. As a result of this reunion, Harry began playing again after a sixteen-year hiatus. With Ron Feuer and another old friend, Abraham Laboriel, he went on to form the trio GEM. In 1996, Harry's Farmers Market sponsored an evening of music with GEM, the Atlanta Symphony Orchestra under the direction of Yoel Levi, and a jazz orchestra made up of superstars from L.A. and New York. Harry produced the event and performed and conducted as well. This event allowed Harry to reaffirm and develop many close friendships with some of the world's greatest living jazz musicians, one being Lew Soloff.
