Released in October of 1976, Leftoverture rose as high #5 on the Billboard Pop Albums in 1977, which to this day has solidified its place as one of the most influential progressive rock albums in modern times. Kansas experienced with a wide variety of different instruments that created a unique sound that has yet to be truly replicated. While still featuring the expected instruments characteristic of a rock band of its time, the band reached beyond the likes of guitar, bass, and drums, and incorporated other instruments into the fold that included piano, violins, violas, organs, vibraphones, and analog synthesizers. The reward is for the listener, as this exposes us to a style of progressive rock that has little been explored, both back then and to this day. The lyrical content is deeply psychological, dealing mostly in the realms of human emotion, intuition, death, and ancient philosophy. The lyrical themes blend with the music progression in unison creating a music that is way before it's time.
