"Keith Tippett (born Keith Graham Tippetts; 25 August 1947) is a British jazz pianist and composer.

Tippett was born in Southmead, Bristol. The son of an English father who was a policeman and an Irish mother name of Kitty. Keith wrote music dedicated to her after she died. Keith was the oldest of three siblings and had Clive and Thomas as brothers. Tippett went to Greenway Secondary Modern school in Southmead, Bristol. He formed his first band when he was fourteen with school friends, such as Richard Murch, Mike Milton, Terry Pratt and Bob Chard. They were called the KT Trad Lads performing Traditional jazz. Later Keith formed a modern jazz trio in Bristol and played regularly at the Dugout Club in Park Row, Bristol. He studied Piano and Church Organ, was a chorister and played with the school and Bristol youth brass bands. He moved to London in 1967, to pursue a musical life.

In the late 1960s, Tippett led a sextet featuring Elton Dean on saxophone, Mark Charig on trumpet and Nick Evans on trombone. Tippett married singer Julie Driscoll and wrote scores for TV.

In the early 1970s, his big band Centipede brought together much of a generation of young British jazz and rock musicians. As well as performing some concerts (limited economically by the size of the band), they recorded one double-album, Septober Energy.

He formed, with Harry Miller and Louis Moholo a formidable rhythm section at the centre of some the most exciting combinations in the country, including the Elton Dean quartet, and Elton Dean's Ninesense. Around the same time, he was also in the vicinity of King Crimson, contributing piano to several of their records including "Cat Food" (and even appearing with them on Top of the Pops). His own groups, such as Ovary Lodge tended towards a more contemplative form of European free improvisation. He continues to perform with the improvising ensemble Mujician and more recently (2006) Work in Progress.

Tippett has appeared and recorded in a wide variety of settings, including a duet with Stan Tracey, duets with his wife Julie Tippetts, solo performances, and appeared on three King Crimson albums."

"Paul Dunmall was born 1953, Welling, Kent; saxophones, clarinets, bagpipes, miscellaneous wind instruments.

As told to Watson (1989), Paul Dunmall was a working class lad from Welling who left school at 15 and spent two years repairing instruments at Bill Lewington's shop in Shaftesbury Avenue, London. He turned professional at 17 and, following two years touring Europe with a progressive rock band (Marsupilami), joined the Divine Light Mission, a spiritual movement led by Guru Maharaj Ji and moved from London to an ashram in America. He told Isham (1997), 'I moved to an ashram full of musicians - a music ashram - but it was still spiritual practice. That gave me a spiritual understanding through meditation, Coltrane's music, and all the rest of it, led me to that, and that's been a fundament in my life ever since - that I can actually sit down and meditate and forget my body. I realise how important meditation is in my life... but I don't do it so much these days.' During the three years he lived in America, Dunmall played with Alice Coltrane (in a big band with the Divine Light Mission) and toured for twelve months with Johnny 'Guitar' Watson.

Back in England, he played with Danny Thompson and John Stevens as well as folk musicians Kevin Dempsey, Martin Jenkins and Polly Bolton and then, in 1979 he became a founder member of Spirit Level (Tim Richards, piano; Paul Anstey, bass; Tony Orrell, drums), staying with the group until 1989. During his time with Spirit Level, Dunmall joined the two-tenor front line group Tenor Tonic with Alan Skidmore (1985), played and broadcast with Dave Alexander and Tony Moore in the DAM trio (1986) and formed the Paul Dunmall Quartet with Alex Maguire, Tony Moore and Steve Noble (1986).

In 1987 Paul Dunmall joined the London Jazz Composers Orchestra, being a constant member and appearing on all their recorded output from that date onward. The following year the improvising collective quartet Mujician was formed by Keith Tippett, Dunmall, Paul Rogers and Tony Levin and has continued to be a regular performing, touring and recording group, sometimes augmented by other musicians. Dunmall has also played in a trio with Keith and Julie Tippetts and in Keith Tippett's big band Tapestry. Two other duos have also sprung out of Mujician: Dunmall with Tony Levin (two CD releases) and Dunmall in folk-influenced outings with Paul Rogers. Another regular playing partner throughout this period and up until the present includes Elton Dean.

In 1995, two trios were formed, the first with Oren Marshall, tuba and Steve Noble, percussion, the second with John Adams, guitar and Mark Sanders, percussion, these sometimes coming together as a quintet. More recently, Dunmall has played in another reeds/guitar/drums trio with Philip Gibbs and Tony Marsh and there appears to be regular crossover between all these players. The Paul Dunmall Octet was founded in 1997."

Dunmall also has released a large number of albums and a box set on the UK FMR label, in various configurations and instrumentation.
