Please answer the following question: Information:  - Jazz fusion (also known as jazz-rock) is a musical genre that developed in the late 1960s when musicians combined aspects of jazz harmony and improvisation with styles such as funk, rock, rhythm and blues, and Latin jazz. During this time many jazz musicians began experimenting with electric instruments and amplified sound for the first time, as well as electronic effects and synthesizers. Many of the developments during the late 1960s and early 1970s have since become established elements of jazz fusion musical practice.  - The Grammy Award for Best Vocal Arrangement for Two or More Voices was awarded from 1977 to 1986. From 1977 to 1981 it was called the Grammy Award for Best Arrangement for Voices. The award is presented to the arranger of the music.  - In music, an arrangement is a musical reconceptualization of a previously composed work. It may differ from the original work by means of reharmonization, melodic paraphrasing, orchestration, or development of the formal structure. Arranging differs from orchestration in that the latter process is limited to the assignment of notes to instruments for performance by an orchestra, concert band, or other musical ensemble. Arranging "involves adding compositional techniques, such as new thematic material for introductions, transitions, or modulations, and endings... Arranging is the art of giving an existing melody musical variety".  - A cappella (Italian for "in the manner of the chapel") music is specifically group or solo singing without instrumental accompaniment, or a piece intended to be performed in this way. It contrasts with cantata, which is accompanied singing. The term "a cappella" was originally intended to differentiate between Renaissance polyphony and Baroque concertato style. In the 19th century a renewed interest in Renaissance polyphony coupled with an ignorance of the fact that vocal parts were often doubled by instrumentalists led to the term coming to mean unaccompanied vocal music. The term is also used, albeit rarely, as a synonym for alla breve.  - Janis Siegel (born July 23, 1952) is an American jazz singer with the vocal group The Manhattan Transfer.  - Jazz is a music genre that originated amongst African Americans in New Orleans, United States, in the late 19th and early 20th centuries. Since the 1920s jazz age, jazz has become recognized as a major form of musical expression. It emerged in the form of independent traditional and popular musical styles, all linked by the common bonds of African American and European American musical parentage with a performance orientation. Jazz is characterized by swing and blue notes, call and response vocals, polyrhythms and improvisation. Jazz has roots in West African cultural and musical expression, and in African-American music traditions including blues and ragtime, as well as European military band music. Although the foundation of jazz is deeply rooted within the Black experience of the United States, different cultures have contributed their own experience and styles to the art form as well. Intellectuals around the world have hailed jazz as "one of America's original art forms".  - m-pact is a Los Angeles, California-based "pop-jazz vocal group" founded in June 1995.
