Carcel sin rejas, by DavidKBD (who will always be “the Portent Rider guy” to me).
Oddly when I looked into it it expecting there would be a bunch more songs like this, it seems like this guy mostly did videogame-type music. His “Dreamland” album was pretty good, particularly in its 2013 update, so after this album and a couple other songs that’ll be up next.
In any event, here’s a song from the same album (El ladrón nocturno) as Portent Rider, and similarly good.
