A beautifully filmed rendition of John Cage’s composition Forever and Sunsmell, performed by Dorothy Gal, Christopher Salvito, and Jessica Tsang and filmed and recorded by Christopher Salvito.
The title and text of Forever and Sunsmell are from 26, one of 50 poems (1940) by e.e. cummings. Some lines and words have been omitted, others have been repeated or used in an order other than that of the original. The humming and vocalise (not part of the poem) are an interpolation.
That’s from the video description. There’s a longer analysis of the piece at allmusic.com that talks about its place in Cage’s artistic development. For the complete text of the original poem, click through to Vimeo.
