I think that any musical instrument can be put to good creative use, but I'm particularly fond of the flute, followed by the violin.  Needless to say I'm a big fan of Jethro Tull, and if you like a strong violin presence I can recommend Ankh's same titled album.  A couple of bands whose expert playing of classical or traditional instruments are Omnia, a celtic folk band from the Netherlands whose members play didgeridoo, slideridoo, harp, hurdy-gurdy, piano, bodhrán, guitar, mandolin, violin, and banjo!  Also the Canadian folk rock band The McDades are pretty good.  The latter two bands mentioned are not on this site but do have progressive elements and are worth a listen!

There's Cornet on Red, but no Clarinet. You might be mistaking the oboe for clarinet.  

I always love piano and church organ for the right moments in certain songs (such as Repent Walpurgis from Procul Harum, and Close to the Edge from Yes for organ, and various other songs such as Love Reign O'er Me by The Who for piano.  Piano is unlimited though).  I also love full orchestras but if I had to pick out one specific instrument from an orchestra it would have to be Cello.  The cello lead in the Exogenesis Symphony from the new Muse album "The Resistance" is spectacular.
