The Opus is an instrumental hip-hop project out of Chicago, and they’ve just released their latest EP, Praying Mantis.  The EP is jam-packed with seven dense tracks of strong beats and interesting samples, with a flair for ambient openings.  Oddly, the EP begins with “Divorced”, labeled as a bonus track.  I have yet to see a version of the EP without the “bonus” track, and I couldn’t imagine a better opening to the EP.
