In this kind of post, I'll post a song of the day in classical, jazz, and contemporary pop, rock, or experimental music. This is just to develop a resource of different kinds of music, and maybe pique interest in something you haven't listened to before!
Classical: Chopin's Nocturne No. 2 in E-Flat Major, Op. 9 No. 2 Chopins nocturnes were a series of piano solos meant to evoke the feelings of the night. https://open.spotify.com/track/41jwqis6FPDjSKvP80zGtr
Jazz: Charlie Parker's 'Blues for Alice,' famously also known as 'Bird Blues.' Parker's Bebop classic became a standard for jamming jazz bands. https://open.spotify.com/track/77u2aLfY8KGmMZIDy0RRns
Rock, Pop, or Experimental
CAN's 'Vitamin C.' This experimental jazz/rock song was one of the foundational tracks of a genre known as 'krautrock,' a German style of modern experimental music which blended rock, jazz, electronic music, and musique concrete (https://en.wikipedia.org/wiki/Musique_concr%C3%A8te). Krautrock has influenced groups in modern times such as Radiohead, Daft Punk, LCD Soundsystem, and a great deal of Hip Hop!
If anyone else wants to submit some songs they love, it would be great to get other people's recommendations as well! This should be open for the whole community. Email me any suggestions at firstname.lastname@example.org.
