Furthermore, Shpongle uses the voice work of many artists, and also samples from other songs. In the song "A New Way To Say Hurray," a sample from an African tribe song is used. The production quality and composition of Shpongle's music blows me away each time I listen to them.
All in all, just check them out, they're amazing. If you are into said "psychedelic substances" listen to them while under the influence and you will not regret it. I leave you with another great song, the Star Shpongled Banner.
