In that case I would suggest to just go through the top-rated / top-favorited modules on ModArchive, really. There's a lot of well-known melodic tunes in there.

Hello,

In the beginning, i was sure there were something to do with the demoscene.

But it can be extend to the whole module sceene, of course.

I've listened the compos of the metal compo 2006, and there are nice things. But they say they didn't want that kind of music achievement. I've understood that their foremost search is nice melodies which could be replayed with guitars.
If there are already nice riffs, it's a «plus»  of course.

It's a bit hard to describe. I would suggest, if you have time, to listen some of their remixes to understand better what they like to remix. You'll see that there were not necessarily guitars in the original.
May i suggest:

You see, only videogames for the moment. That's why i was thinking of the demoscene and it's potential (seldom exploited in remixes, which is a shame ).

Do you specifically look for "demo-ish" tracks or anything from the tracking scene? Because there was a whole sub-scene in the tracking scene just producing metal music, for instance.

Grospixels is a musical band, specialized in videogames music remixes:

Recently i was talking with their guitarist.

I've suggested him exploring demo side of the soundtracker scene.

He has nothing against the idea, but asked me if i knew some modules with cool guitars riffs and nice melodies.
Except « Cerebal Beres » (Tip & Mantronix), i couldn't give any.
Of course, there are modules like « Guitar Slinger ». But to their own terms « the quality is very high with very nice samples , and there is little interest to remix this, for getting the same thing at the end ».

May be some Necros or Moby ? But i think their feeling will be the same.

Do you know some catchy modules which could be replayed in a rock fashion ?

You can see there what they can do, with more or less known musics:

Turrican 2 (Chris Huelsbeck): https://www.youtube.com/watch?v=nU_-76G7VyA
Gauntlet 3 (Tim Follin): https://www.youtube.com/watch?v=WA564W8ANUs

But they have nice underdog remixes too:

You can load high quality MP3 on their website for free.

Alright, the earlier file has been rejected.

Can the screener upload the second file instead of the first (while leaving the filename as the first)? I did some adjustments to the instrument texts and the title. Thanks!

It's fast again!!
