Steve Howe fans (of which I am one, but an apparently ignorant one) -- what exactly is a vachalia?

Of all the old-school synths out there, I prefer the sound of an ARP 2800 (if memory serves). And the earlier poster is right, Tony Banks used the mellotron choir as well as anyone.

Nice flautist for the old band Jade Warrior.

Beautiful violin on several Roxy Music tracks when Eddie Jobson was with the band. And of all bands, Hawkwind had a very proficient violinist/keyboardist for a number of albums in Simon House. HW isn't exactly known for their musical proficiency, but House is very, very good.

Ian Anderson likes the penny whistle, too.

The Psychedelic Furs are hardly a progressive band, but I saw them on tour with a cellist, and it was very effective. The lady made herself part of almost every song, and played with a lot of energy.
