Iannis Xenakis - Eridanos [w/ score]

Eridanos was written in 1972 for 60 string instruments (16, 14, 12, 10, 8) and
brass (2 tubas, 2 trombones, 2 horns and 2 trumpets). The score features no
woodwind nor percussion instruments. And contrary to other orchestral pieces by Xenakis, each string instrument does not play an individual part.
First violins, second violins, violas, cellos and double basses are simply divided into two groups.Perhaps one of the most striking features of Eridanos is the absence of glissandi, considering that it was composed just after Xenakis had used random-like melodic contours and just before he developed the idea of arborescence, which relies mainly on continuity as one of its main characteristics. In this context, Eridanos appears
as if given in parentheses.
Xenakis said very little the work. He did not mention it in his writings nor in
his main interviews. The only sources of information available are the notes to
the score and files found in the Xenakis Archives on deposit at the Biblioth`eque nationale de France.
