What music do you want to play really loud?

Someone mentioned Finlandia.

I love that piece! Its very unique! Just so happens I popped in on the table for the first time in years yesterday!

How about "Swan of Tuonela" as well?

Sibelius rules!

One totally different, more obscure track, there's a lot of good vintage Savoy Brown worth cranking as well!

Also add "One of these Days", "Echoes" and "Fearless" from "Meddle" by PF to the list as well.

Mapman, yes, I agree with all of the above. Another good one from Sibelieus is the first movement of Sym. No. 4.

Add the albums "Learning to Crawl" by The Pretenders and " Relayer" by Yes with special mention for "Gates of Delirium".

I can only take "Styx" in limited doses, but cranking the volume helps a lot with this group in particular. "The Grand Illusion" album is an excellent crank from start to finish.

I'd toss some of the better tunes from "Sweet" in this same category as well. Cranking "Love is Like Oxygen" and several other of their better known tunes is highly recommended.

Ditto for "Inside Looking Out" by Grand Funk. Crank this on your favorite high end system and enjoy!!!!
