I first played solo, just a short piece, in 1982 at the Workers' Music Association in Notting Hill Gate.
To quote from a 1998 Rubberneck piece:
"After a few concerts I'd learnt a lot about making connections - but had also noticed recognisable pieces beginning to develop. I quite liked this, but worried about what it meant for long-term solo work. For a while, I almost envied composers; able to wrap up a piece, send it out into the world, and move on to the next. But a lot of the pleasure in giving solo concerts is connected to the hope of finding, spontaneously, some music you didn't really know about beforehand. Playing pieces is too close to playing routines and a concert is an opportunity for much more. As a live performer, improvising usually just feels better - less acting, less theatre, and more chance for a little magic. By way of a bonus, this means engaging with what Derek Bailey described as a "search for whatever is endlessly variable".
Whilst still close to my feelings about solo concerts - another side of solo work has been to develop compositional ideas for CD: from the 1992 multitracks on Thirteen Friendly Numbers to the microphone-based work on Invisible Ear.
These ideas have since informed many live concerts.
One aspect was explored in 2010 with Stephen Moore, whose Max patch enabled live multitracking via 15 speakers at Issue Project Room in Brooklyn (review).
I have also had the opportunity to create solos specifically for large or especially characterful acoustics. Two CDs have come from inside the giant Oya Stone Mountain in Utsunomiya, Japan.
Resonant Spaces was a 2006 Arika tour in Scotland and the Orkneys which visited sites specially chosen for their extraordinary acoustics.
Later that year I played, for Resonance FM, in Oberhausen's famous 200m high gazometer .
In 2010 these ideas were continued, with Joe McPhee, at artist James McGee's The Hill in the West Texas Desert near El Paso. A day reviewed in Signal to Noise.
Recent site-specific works include in the medieval vaults of Southampton (WIRE review), Dunston Staiths, and Newhaven's 19th century Fort.
