the microt. guitar web site

Need some help :

Are these folks microtonalist guitarists ?
David Seidel
Scott Armel
Vito Ricci (read that he performed at AFMM)
David Tanenbaum
Joe Morris (listed in the entry for Joseph Manieri's disc on Op de Coul's
discography

Anyone know what's up with David Canright's site ?
