Don Ellis born 25 July 1934

Donald Johnson Ellis (July 25, 1934 – December 17, 1978) was an American jazz trumpeter, drummer, composer, and bandleader. He is best known for his extensive musical experimentation, particularly in the area of time signatures. Later in his life he worked as a film composer, contributing a score to 1971's The French Connection and 1973's The Seven-Ups. 

Ellis was born in Los Angeles, California, on July 25, 1934. His father was a Methodist minister and his mother a church organist. He attended West High School in Minneapolis, MN. After attending a Tommy Dorsey Big Band concert, he first became interested in jazz. Other early inspirations were Louis Armstrong and Dizzy Gillespie. He graduated from Boston University in 1956 with a music composition degree. 

Ellis' first job was with the late Glenn Miller's band, then directed by Ray McKinley. He stayed with the band until September 1956, when he joined the U.S. Army's Seventh Army Symphony Orchestra and the Soldiers' Show Company. Ellis was transferred to Frankfurt, Germany for duty. In the Army band, Ellis met pianist Cedar Walton, and saxophonists Eddie Harris and Don Menza. While in that band Ellis had his first opportunity to compose and arrange for a big band. 

After two years, Don Ellis left the Army band and moved to Greenwich Village in New York City. He was able to get some work, but mainly with dance bands and other local work. He toured briefly with bandleader Charlie Barnet and joined the Maynard Ferguson band in spring of 1959. He remained with Ferguson for nine months. Shortly thereafter, Ellis became involved in the New York City avant-garde jazz scene. He appeared on albums by Charles Mingus, Eric Dolphy, and George Russell, working in that sextet for two years. Under his own name, Ellis led several sessions with small groups between 1960 and 1962. The last one, Essence, was recorded in mid-July 1962. 

During 1963 in New York, Ellis formed the Improvisational Workshop Orchestra. Uunusual artistic devices were employed, such as performers using cards to determine event orders, and musicians using their instruments to interpret a painter's work. Some uncommon musical elements were employed, such as the use of Arabian rhythms and scales, and foot shuffling. However it was in 1965 when he put together his first orchestra that he really started to make an impression in jazz. 

Ellis's big bands were distinguished by their unusual instrumentation, the leader's desire to investigate unusual time changes (including 7/8, 9/8, and even 15/16), its occasionally wacky humour, and an openness towards using rock rhythms and (in later years) electronics. Ellis invented the four-valve trumpet and utilized a ring modulator and all types of wild electronic devices by the late '60s. Around this time, Columbia Records producer and A&R man John Hammond sought to recruit the band for the label. 

                              

The band was signed, and was in the studio in September 1967 to record Electric Bath, which was released the following year to wide acclaim, was nominated for a Grammy award, won the 1968 Down Beat "Album of the Year" award, reaching No. 8 on the Billboard jazz charts. The song "Indian Lady" became one of the band's most popular tunes. "Open Beauty" featured Ellis in an echoplex trumpet solo, an innovative combination of acoustic instruments and electronic technology. Ellis would record six other albums for Columbia and continue to develop the "electrophonic trumpet" over the next five years. 

By 1971, his band consisted of an eight-piece brass section (including French horn and tuba), a four-piece woodwind section, a string quartet, and a two-drum rhythm section. A later unrecorded edition even added a vocal quartet. In 1974, Ellis became interested in the music of Brazil, even studying Portuguese so as to better communicate with indigenous musicians. He led a live band around this time called the Organic Band, which was a stripped-down version of the Orchestra that had no electronic instrumentation or modification (save for amplification). The band also featured a vocal quartet. 

After suffering a mid-'70s heart attack, Ellis returned to live performing, playing the "superbone" and a later edition of his big band featured Art Pepper. Ellis's last known public performance took place on April 21, 1978, at the Westside Room in Century City. After this, his doctor ordered him to refrain from touring and playing trumpet because it was too stressful on his heart. 

On December 17, 1978, after seeing a Jon Hendricks concert, Ellis suffered a fatal heart attack at his North Hollywood home while making an early morning meal for his parents. His heart condition is believed to have been cardiac arrhythmia. He was 44. Ellis was buried in the Sheltering Hills section, of Forest Lawn Memorial Park, in Hollywood Hills, California.
