"Roundness" was originally composed as an electronic piece, but in this performance the parts of the main synth are rearranged for the xylophone: these are two sequences that are repeated for almost the whole song, each in 5/4 but which, due to the bass harmonic rhythm, they are also perceived in 4/4, 3/4 and 7/4.
Some of the electronic sounds have been retained, the main parts of the song are all actually played with melodic percussion.

Listening with headphones / earphones is recommended.
