I think (and hope) that these kind of small mp3 samples are allowed under the "fair use" rule. If not, my bad
Listen to the sample attached to this post, and if you manage to identify what it is, post a reply with the smallest hint possible (e.g. singer comes from Spain, guitar player uses Gibson mostly, etc ...) If others already posted hints, then be careful not to reveal too much with another hint.
POST THE ANSWER!!
