i found this wicked solo guitarist on youtube, but he's not signed to any record label yet:

the details int the upper right give a link that says "song download" and a link to a japanese download purchase site but i have no idea how to navigate it.
Does it look like they also sell cds or just downloads? I want to support this guy to put out more awesome instrumentals.

I checked his Youtube Channel, and that actually links to a different page on nextmusic.net than the link at the youtube page you probably used.

You can download 5 of his songs here:

They're free, and there doesn't seem to be any way to financially support him yet.
