Soledad Vélez, Chilean-born but settled in Spain, is one of the, if not the, best voice(s) I cud hear at the festival. Her singing style reminds me a little bit of some musicians, like Édith Piaf or Joan Baez, who made vibrato their trademark. She is not too familiar in my (her) country. I know that someday her talent will go a long way, though. Let things take their course!
Check out her bandcamp where she's got the first two EPs up for grabs.
Here is a photo that I took of her at the festival this past weekend.
