I am looking for music that you have to listen to, at least once in your life, not for the popularity that the song or the artist may have, because anyone can be popular, but for its transgression in society, either for its sound or its message, an example of message can be the album wall by pink floyd, another example, but referring to the sound, can be the discography of tool, also less known people like dr steel are valid, what counts in the end are the points that I mentioned, the sound and the message. It doesn’t matter the musical genre you recommend me, the language either, I can translate it without any problem, although being a spanish speaker, it would be good to emphasize artists that make music in spanish, if you don’t know hispanic artists, it’s ok, I’ll listen to the music you recommend me anyway, I’m waiting for your lists.
