Does anybody know some neoclassical thrash or speed metal releases? Something like Helstar's Nosferatu

Also I'd like to hear something like Speed Metal Symphony.

Just Mekong Delta.

(Thrash, not Speed)

The first three Blind Guardian albums. They started out speed metal and with plenty of neoclassical riffage+solos.

I agree 100% with the recommendation for the early Blind Guardian albums. I assume you know all of Iron Maiden's stuff (e.g., Powerslave).

I'm late responding, but here are a few more which you might like:

Artillery - By Inheritance
Brimstone - Carving a Crimson Career
White Skull - Public Glory, Secret Agony
Hallows Eve - Monument
Heaven's Gate - Livin' in Hysteria
Intense - As Our Army Grows
maybe: Bloodbound - any (e.g., Book of the Dead)

Oh, and I think Stormwarrior might be worth a try, too (particularly if you decide you like the early Blind Guardian stuff).

LAST RITE - "The Beginning of the End" Demo, 1990
ANICENT CREATION - Moonlight Monument
ATTACKER - Giants of Canaan
APOCRYPHA - all
VON HELLSING (us/ny) - The Fiend Who Comes at Dawn - 1987 demo
XENOPHILE - Systematic Enslavement of Consciousness
SACRAL RAGE - Illisions in Infinite Void
REALM - Endless War
ALTERED STATE (NJ) - demo
CAULDRON BORN - all

Coroner's debut, R.I.P., has a good deal of shredwork, including some instrumental stretches.

Butcher - Astral Karma.

Check out Maelstrom's 'This Battle to Make History, Yet History Never Comes' demo. Ripping progressive/neoclassical power/speed/thrash with an insane vocalist.

Cacophony? anyone?
