Pink Floyd – Echoes

I could listen to this almost 24 minute song 3 times a day.  When it plays, the visuals I get are of alien beaches,  still clear lagoons, and aquatic night life.  It builds to the end with a slowly building sunrise that apexes at the moment the otherworldly sun breaks the horizon (Gilmour finally fulfilling our anticipation with his expert chops), then reprises itself, tempered with my now perceived day flavor.  Along the way are an aural narrative of the exploration of the depths, and a stop to listen to some very vocal life forms beneath the waves.

The lyrics are classic Floyd, and decorate the song competently, but it is the music that is the  star in the this tune.  If there is only one song that I say anyone must listen to, it would be this one.
