Jón Leifs is brilliant! What you think of Baldr, opus 34 and Requiem? Those are my favourites besides Hekla ópus.

The recording I have of Baldr is okay (conducted by Paul Zukofsky). The anvil pounding sounds and whatnot are obviously sampled...which kind of dissapointed me...

I don't have a copy of Hekla at the moment...though I've gotten the BIS release from the library a coupl'of times. He's brilliant...but like Holmboe...some better recordings need to be made (well, except for the Holmboe symphonic cycle on BIS, which is amazing...there's so much more, though. Recordings of his string quartets and chamber orchestra pieces exist. From what I can tell, it's all on that DaCapo label...the performances are a little lackluster in my opinion).

The Simax label is a recent find for me...some really interesting and obscure stuff can be found. Tema con variazioni by Ludvig Irgens Jensen conducted by Odd Gruner-Hegge is a good example.

I find Gruner-Hegge records sometimes in Goodwills and thrift shops...but they're always too mutilated to listen to.

Purcell
Mozart
Verdi
Puccini
Richard Strauss

I can't decide on five, but my favorites are:
Shostakovich
Schnittke
Rachimanoff
Stravinsky
Mozart
Bartok
JS Bach
Debussy
and if you would put Steve Reich in the classical vein him too.
THose are the ones that I can think of off the top of my head, I'll probably have to add some later.

Might as well chime in with the rather obvious choices of...

BEETHOVEN (the greater composer of symphonies as well as the greatest composer for the piano)
MOZART (the king of piano concertos, opera, and anything giving the clarinet center stage)
BACH (sometimes I find him dry and academic, especially in the Well-Tempered Clavier, but in the right mood, I'm convinced that he had no equal in music)
SCHUBERT (gorgeous chamber and piano music, he's probably spent more time in my CD player in the last month than anyone)
BRAHMS (not as sizeable an oeuvre as the other four, but just about everything is gold)

Of course, they're obvious for a reason.

I will have to check out Schubert and Brahms in the very near future.

W. A. Mozart (my favourite in absolute!!!! i love his requiem)
L. V. Beethoven
Heyden (He is great as well, i discovered him from the Kubrick movie "Barry Lindon")
R Wagner
A Vivaldi

You mean F. J. Haydn?

He must be thinking of Handel. Haydn is nowhere to be found in "Barry Lyndon".

John Williams
Samuel Barber
Beethoven
Handel
Motzart
