I loved that Laydock 2 arrangement. About that Castlevania arrangement, I think it's very well played and interesting to watch and to listen, but it seems they changed the chord progression just for the sake of changing. I don't mind anyone making the arrangement their own, but I don't think they quite succeeded here since it's a bit on the conventional side, otherwise. Not that there's anything wrong with that, of course; my own arrangements are almost always super conventional.
Will check both channels for more music, of course! Thanks for the tips, @ren 
Those castlevania guys can play... but those chords... O_o
You especially like them chords? That's cool man.. 
I'm not a music composition buff, so maybe I'm missing something here. He (it's 1 guy 
) mixed the default arrangement with the Dracula X Chronicles version, and he most of times tries to add some original arrangement ('improvisation') from his own hand.
I think it came out pretty well, something different from the gazillion VK covers out there that follow the standard arrangement.
Btw, something I posted about before, a while ago: ATM you can vote again for what he's gonna cover next (till tomorrow midnight CST actually - that's 07:00 CET Monday morning), check out his latest vids for that.
Rather curious how his Space Manbow cover will turn out... (one of the tunes that won in a previous voting round :))
I think his DOOM 64 for DOOM II (D64D2) (playlist) work is pretty cool, and e.g. the Doom 3 Main Theme Redux. And his Silent Hill 2 - Theme of Laura cover comes to mind, which I think is underrated :)
@Parn Welcome, yeah, I also really dig that Laydock arrange, I hope he'll be back with something new before the end of this year.. ;-) If you're into it, also check his DAITA & U.N. Squadron covers (or simply his whole discography there ;))
Nah, those chords made no sense, but the playing- and production skills are way above average. I've nothing to complain about that.
I guess he should work a bit on his transcribing- and arranging skills to avoid playing wrong stuff very well. I like well played good stuff more, you see

I'm not familiar with DAITA but sure will check those as well. I was listening to his Gradius stuff here at my aunt's, where I'm currently staying, and my cousin, who isn't a VGM buff, just popped up to enjoy it with me. He liked it a lot, too.
