Over the last 10 or so years, I have played on a regular basis with:
Vocals, flute, whistle and bazouki for this respected Celtic-rock outfit.

Stuck In D'80s
An international collective of 'C64 scene' musicians (including Mark Knight, Jon Hare, Marcel Donné, Reyn Ouwenhand and Andreas Wallstrom) who perform at various Games Conventions such as BIT Live, Retrovision and CGEUK, and with whom I play electric guitar, flute and WX5 Wind controller.
Derbyshire's longest established band, with whom I performed a Jethro Tull 'tribute' show on (suprise suprise) flute (and some guitar, with a capo on the 3rd fret, just like Ian).
Multi-instrumental samply-worldy-classically-musical noodling at its finest.

Thee Na Shee
Whistle, flute, guitar and keyboards for this (now sadly defunct) most accomplished Celtic band. Included the talents of Dave Sturt, Jeff Davenport and Rob Launder, three of the Midland's finest musicians.
Tomorrow's Ancestor
Eco-festival favourites, inspired and led by Brian Boothby,
Healing Field music Supremo. Again, now sadly defunct, though the spirit lives on :)
