"Pedal Power - the virtuosity of organist Barbara Dennerlein. ...a new and distinctive voice on the Hammond has been turning that world upside down... Barbara Dennerlein has been rewriting the rulebook. She combines incredible co-ordination of hands and feet with complete rhythmic freedom. On her brief London appearance, she demonstrated this with originals..., shifting between different metres and chorus lengths...she proved she could be just as inventive and free within the standard repertoire. Opening with a bluesy tribute to Jimmy Smith she showed just how far she has moved forward from his style of playing.

Jazz Rock/Fusion definition

1. Jazz Fusion is jazz that is strongly influenced by other styles of music. Jazz fusion is an ambiguous term that provides the first level sub-set down from Jazz. Jazz rock is a sub-sub set from jazz via jazz fusion. The ambiguity comes from an American tendency through the 90's and until now, to freely interchange jazz rock and jazz fusion, when in fact the latter term covers most hybrids of jazz fused with other forms of music. The roots of jazz rock can be traced back to RnB influenced soul-jazz artists such as Les McCann, Grant Green and Jimmy Smith, and young British jazzers such as Graham Bond, Ginger Baker, John McLaughlin, Jack Bruce, Georgie Fame, who were forced to use electronic instruments because the local club's acoustic instruments were reserved for the older established jazz musicians. Probably the first jazz artists that released recordings that mixed modern rock (circa 60s) with jazz were Larry Coryell, Jeremy Steig, Charles Lloyd, The Soft Machine, and The (Jazz) Crusaders. Meanwhile rock artists such as Cream, Grateful Dead and The Jimi Hendrix Experience were getting a lot of publicity and fame with their lengthy improvisations based on blues, rock, psychedelia and some jazz. These rock artists had an impact on Miles Davis who generated a lot of media attention to this new jazz-rock genre with his Bitches Brew album. From there the genre grew and exploded into numerous different directions. One of these directions was brass rock as exemplified by bands like Dreams, Chicago, BS&T and If. These bands combined elements of jazz, rock and classical music with arrangements for brass and woodwinds.


2. Many other styles of music have been combined with jazz to create fusion including traditional music from around the world, R'n'B, rock, electronic music and pop music and jazz from Africa, Latin America, India and other places. One of the earliest examples of the use of the term fusion comes from the Indo-jazz fusion of Joe Harriott and John Mayer. Some of the more popular early practitioners of fusion included Weather Report and Herbie Hancock's Sextant. A few years later Shakti appears on the scene and expands the boundaries of fusion further, foreshadowing the World Fusion movement of the 90's.


3. In part Nu.jazz grew out of the British acid jazz scene of the late 80s and early 90s, whilst modern leaders of nu.fusion cite Miles Davis and Jon Hassell as the godfathers of the genre. As the genre began to develop it took on other influences such as world beat/jazz fusion, psychedelic trip-hop, post-rock and mixtures of ambience with modern jazz. The jazz with electronia experiments that Jon Hassell was conducting in the late 80's, with the likes of Eno, were to be a major influence especially on the dance side of nu.jazz, sometimes known as nu.fusion. Three main elements make nu.jazz different from the more traditional jazz (rock) fusion. First of all there is less of an emphasis on instrumental virtuosity in nu.jazz (especially nu.fusion). Second, more use of electronics (especially skilled turntablism) and studio trickery that emphasizes sound textures. Third, nu.jazz tends to use more modern rhythms such as drum'n'bass, hip-hop, post-rock, and various mixtures of world beat rhythms. Progressive nu.jazz artists such as Bugge Wesseltoft, Nils Petter Molvaer and the Esbjörn Svensson Trio (E.S.T.), combine complicated compositions with modern rhythms to create new unheard of soundscapes - while the former two are leaders of nu.fusion, and with more emphasis on jazz playing, EST have been the leaders in straighter nu.jazz. Nu.jazz is loosely connected to other newer jazz fusion genres, particularly the more progressive live, jazz jam bands such as Medeski Martin & Wood or Garaj Mahal. It may seem that the only difference between the two genres is the country the artist is from or what scene they came up through.li>
   

Jazz fusion https://en.wikipedia.org/wiki/Arrangements" rel="nofollow - arrangements vary in complexity. Some employ groove-based vamps fixed to a single key or a single chord with a simple, repeated melody. Others use elaborate chord progressions, unconventional time signatures, or melodies with counter-melodies. These arrangements, whether simple or complex, typically include improvised sections that can vary in length, much like in other forms of jazz.

As with jazz, jazz fusion employs brass and woodwind instruments such as trumpet and saxophone, but other instruments often substitute for these. A jazz fusion band is less likely to use piano and double bass, and more likely to use electric guitar, synthesizers and bass guitar.

The term "jazz rock" is sometimes used as a synonym for "jazz fusion" and for music performed by late 1960s and 1970s-era rock bands that added jazz elements to their music. After a decade of popularity during the 1970s, fusion expanded its improvisatory and experimental approaches through the 1980s in parallel with the development of a radio-friendly style called https://en.wikipedia.org/wiki/Smooth_jazz" rel="nofollow - smooth jazz . Experimentation continued in the 1990s and 2000s. Fusion albums, even those that are made by the same group or artist, may include a variety of musical styles. Rather than being a codified musical style, fusion can be viewed as a musical tradition or approach."

Taking that definition as reference Barbara Dennerlein does in my opinion certainly qualify because both Funk and Rhythm and Blues are very prominent in her music (as well as for example Latin, Carribean or even Salsa). And these passages "Others use elaborate chord progressions, unconventional time signatures, or melodies with counter-melodies. These arrangements, whether simple or complex, typically include improvised sections that can vary in length, much like in other forms of jazz" and "Rather than being a codified musical style, fusion can be viewed as a musical tradition or approach" most definitely fit her music. Rock is not so much a characteristic of her music, though there are exceptions like "Wow!" from "Hot Stuff" (she once explained in an interview that it was specifically written for her appearance on a German TV-program called "Ohne Filter" meaning "Without Filter"; she thought she needed at least one rock number for that) or the Rolling Stones cover "Satisfaction" from "Outhipped".
