From the album Ad Lib Volume 6, Part 2. I absolutely love the sound of this song. The lead instrument is really cool. Each note plays a chord instead of a single note. So that neat intro you hear is me just punching in one note at a time. It's so cool and fascinating to me. I wish the instrument (Massive X from Native Instruments) had more chord-like instruments.
It also does a bit of vibrato when you hold the note down, which you can kind of hear in what I guess would be considered the chorus/second part.
