This techy drum and bass track started, I think, with the rave stabs you hear through most of the song.  I felt the dub delay on them at about 0:53 really explored the space of the track in an interesting way, and the track built itself out from there.

All that space made things a little empty without something extra to push this along.  The “call and response” basslines in the second part add some much needed lightheartedness to the track, accentuating the rave influence and contrasting the general darkness of the production.
