“Music, of all the liberal arts, has the greatest influence over the passions, and it is that to which the
legislator ought to give the greatest encouragement.” ~Napoleon Bonaparte
There is a great club in Oakland, California called Duende, "an innovative restaurant that brings the Bay Area a new way to experience food, drink, art and live music." Downstairs is a feast for the eyes; the food, Spanish in nature, is a feast. There is a second floor entirely devoted to up-and-coming music.
Duende ~ loosely means 'having soul', a heightened state of emotion, expression and authenticity*
The Wikipedia article, "Duende (art)," does a great job of addressing this word in its myriad current and past usage. I decided to reproduce the article with deletion-edits to suit my purposes: music and the brain. The added commentary of Nick Cave (of Birthday Party fame) at the end, gives a modern perspective which finds duende largely missing from contemporary rock music, the component of 'true sadness' unfound.

"All love songs must contain duende. For the love song is never truly happy. It must first embrace the potential for pain. Those songs that speak of love without having within in their lines an ache or a sigh are not love songs at all but rather Hate Songs disguised as love songs, and are not to be trusted. These songs deny us our humanness and our God-given right to be sad and the air-waves are littered with them. The love song must resonate with the susurration of sorrow, the tintinnabulation of grief. The writer who refuses to explore the darker regions of the heart will never be able to write convincingly about the wonder, the magic and the joy of love for just as goodness cannot be trusted unless it has breathed the same air as evil - the enduring metaphor of Christ crucified between two criminals comes to mind here - so within the fabric of the love song, within its melody, its lyric, one must sense an acknowledgement of its capacity for suffering."
* Duende is often connected with flamenco, the artistic & especially musical term was derived from the 'duende,' a fairy or goblin-like creature in Spanish mythology
