"Trevor Charles Watts (born 26 February 1939 in York) is an English jazz and free-improvising alto and soprano saxophonist. He is largely self-taught, having taken up the cornet at age 12 then switched to saxophone at 18. While stationed in Germany with the RAF (1958-63), he encountered the drummer John Stevens and trombonist Paul Rutherford. After being demobbed he returned to London. In 1965 he and Stevens formed the Spontaneous Music Ensemble, which became one of the crucibles of British free improvisation. Watts left the band to form his own group Amalgam in 1967, then returned to SME for another stretch that lasted until the mid-1970s. Another key association was with the bassist Barry Guy and his London Jazz Composers' Orchestra, an association that lasted from the band's inception in the 1970s up to its (permanent?) disbandment in the mid-1990s.

Though he was initially strongly identified with the avant-garde, Watts is a versatile musician who has worked in everything from straight jazz contexts to rock and blues. His own projects have come increasingly to focus on blending jazz and African music, notably the Moiré Music ensemble which he has led since 1982 in configurations ranging from large ensembles featuring multiple drummers to more intimate trios. He has only occasionally recorded in freer modes in recent years, notably the CD 6 Dialogues, a duet album with Veryan Weston (the pianist in earlier editions of Moiré Music). A solo album, World Sonic, appeared on Hi4Head Records in 2005.

Watts has toured the world over numerous times, run workshops, received grants and commissions, and he has collaborated with some of the great jazz musicians including Archie Shepp, Steve Lacy, Don Cherry and Jayne Cortez. As of 2011, he continues to travel and toured North American with Veryan Weston."

"Liam Genockey (born 12 August 1948) is an Irish drummer.

Genockey was born in Dublin, Ireland. During the 1960s he lived in Plymouth, Devon, U.K, playing in local semi-pro groups, then in the early 1970s playing with Torbay-based rock band Adolphus Rebirth. He was one of the founding members of the early-1970s jazz-fusion and afro prog band ZZebra, later moving on with fellow band-member John McCoy to join Gillan.

He then participated in Amalgam, formed in 1976 by Trevor Watts. Watts' work covers the spectrum of free jazz, electronic, jazz-rock, space jazz and folk-rock. Watts later founded 10-piece Moiré Music Ensemble which included Liam again, plus Peter Knight, an early member of Steeleye Span.

He joined Steeleye Span in 1989 and recorded two studio albums Tempted and Tried and Time, with them, as well as two live albums Tonight's the Night...Live and The Collection in Concert. However, between 1997 and 2001 he was not in the band. He returned in 2001 to record Present--The Very Best of Steeleye Span, and has remained with the band since, though he also remains Paul Brady's drummer for both live and studio performances.

In January 2003, he was involved in the BBC Four broadcast of Free Will and Testament, a programme featuring performance footage of Robert Wyatt.

Liam is easily identified by his long, plaited beard. He currently lives in Hastings."
