'Knopfauge' is a track from Unknown (Kompakt, 2012), the debut album of Saschienne, the duo of Berlin DJ Sascha Funke and French singer and synth player Julienne Dessagne: minimal electronic music built on Moog lines and patient layering.
'Star Guitar' is The Chemical Brothers' slowly blooming 2002 single, built on four bars of acoustic guitar sampled from David Bowie's 'Starman', and the song behind Michel Gondry's famous one-shot train-window video.
