Harmonium

Don't need to think up a funny/cool post title when the band's name is cool enough.

One of the cooler albums I have. Prog rock/folk, not surprisingly.

Cool that you have to open it to know what it is.

Yep, another glorious gatefold. :)

Here's a little info from their Wiki article: "Their second album Si on avait besoin d'une cinquième saison, better known as Les Cinq saisons, was an immediate success. This concept album included five songs, each one representing a season with the last song being a long instrumental representing a fifth and imaginary season. For this album, the band recruited two new members, Pierre Daigneault, playing the flutes, sax, and clarinets and Serge Locat, handling the piano and synthesizer. The group also invited two guests to play on the sessions: Judi Richards, who handles the vocalizations on the instrumental "Histoires sans paroles" and Marie Bernard performing the theremin-like sounds of the Martenot waves. In 2015, Rolling Stone magazine listed this album at number 36 of the best 50 progressive rock album and declared it the best progressive folk album."

Here's a short National Film Board doc about them touring in California...
