The “sketches” from “Sketches” are songs made from samples of other betterwithmusic’s recordings. This is not the first time I use the “self-sampling”. In “Roots” (Arbol) you can hear scraps of Dancing (1974). But the technique to obtain the samples of Arbol and Sketches was different. In Arbol, except the song above, the samples used were created for the occasion. I knew what I wanted and what I needed. I just had to record it, and I did. Small fragments of songs recorded as an independent new song and subsequently used as sample. Original cuts, not bits of other songs.
Here are three of the “sketches”, with its original.
