and arranging experience, as well as from his studies of Indian music, Ellis began to write jazz-based music with the time signatures he had studied with Rao. These included not only 5/4, 7/8, and 9/4, but also more complex rhythmic cycles like 19/8 and 27/16. In the future, Ellis would use many more complex meters, as well as complex subdivisions of more standard meters. Many of these more complex cycles were inspired by Ellis's later interest in Eastern European folk music, such as that of Greece and Bulgaria. Ellis also had a customized trumpet made for him by the Holton company, which he received in September 1965. Its additional (fourth) valve enabled it to produce quarter tones. Some claim that the inspiration for this may have been due to his studies of Indian music, which includes bent pitches that some ethnomusicologists refer to as "microtones". However, it was probably more the result of Ellis's previous involvement with avant-garde classical music, in which many composers were experimenting with Western tonality and intervals, especially Harry Partch, with whom Ellis is known to have met and discussed ideas. All of these unusual elements combined to create a musical experience unlike anything the Monterey audience had ever seen. The Orchestra received thunderous applause and a standing ovation at the conclusion of their first tune, titled "33 222 1 222" in accordance with its subdivision of 19. The band went on to play tunes in 7, 9, and 27, as well as a couple in more standard meters. Portions of the concert were released on Pacific Jazz the following year. The 1998 CD reissue includes several other tunes from the concert; the CD's notes also reveal that one number, "Concerto for Trumpet", was actually recorded a month later at a "Pacific Jazz Festival" in Costa Mesa. (The Monterey performance of that tune was apparently not up to the standards of Ellis and the album's producer, Richard Bock.) Following this successful breakthrough performance, the band performed at the Pacific Jazz Festival in October 1966, and at Shelly's Manne Hole in March 1967, releasing segments of each on 1967's Live in 3 2/3 4 Time (Pacific Jazz). Columbia Records 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
