John Law started classical piano aged four and performed first in public at six. After winning an Open Scholarship he studied piano and composition at the Royal Academy of Music, London, where he won prizes for piano playing. Despite then winning an Austrian government scholarship to study in Vienna with the pianist Badura-Skoda, and receiving encouragement from an early classical influence, pianist Alfred Brendel, he turned to jazz in 1986, forming his first group ATLAS, a mainly freely-improvising trio with Paul Rogers, bass and Mark Sanders, drums.
From 1986 to 1996 John concentrated more on the experimental end of jazz, particularly in his association with the South African drummer Louis Moholo, with the Jon Lloyd Quartet and with his own quartet. The John Law/Louis Moholo Duo recorded the acclaimed CD em>The Boat Is Sinking, Apartheid Is Sinking (Impetus 19322), appeared on British radio and toured extensively in the UK, Germany, Holland, Belgium, France and Canada, appearing at many major festivals. The Jon Lloyd Quartet appeared on British radio, made three acclaimed CDs, the last for Hat Hut called By Confusion, and played at festivals, including the 1995 FMP Festival, Berlin. With his own small groups John recorded and toured in the UK, Germany, Holland, Belgium, Austria, Italy, Russia, Lithuania and Belarus, including many festivals. A later quartet, formed 1993, with Paul Dunmall (saxophones), Barry Guy (double-bass) and Louis Moholo, called Extremely Quartet, toured the UK and appeared to great acclaim at the 1998 Nickelsdorf Festival, Austria. They released the CD Extremely Quartet (Hat Hut CD6199) in 1997. John was also involved occasionally during this period with the Evan Parker Quartet. One-off collaborations also included the Dedication Orchestra, a duo performance with the pianist Keith Tippett and a London Festival concert in a septet with David Murray and Chico Freeman.
While John Law was exploring the more radical and freely improvised areas of jazz he also began a series of solo CDs which were to lead him back to an exploration of his classical roots. The four-CD series Chants (Cornucopia, 1993), Talitha Cumi (FMR, 1994), Pentecost (FMR, 1996) and The Hours (FMR, 1997) Thanatos (FMR, 1997) was based on plainchant and, as well as jazz, explored the history and techniques associated with classical piano as well as introducing certain harmonic elements derived from early and mediaeval music. The CDs received outstanding reviews around the world. Concentrating on this music, John gave concerts in the UK in concert halls, churches and universities, and appeared at major festivals in London, Le Mans and Clusone.
