While members of Cave In are busy with various projects including frontman Steve Brodsky's Octave Museum, Pet Genius and his own solo work, Guitarist Adam McGrath's Clouds, and bassist Caleb Scofield with Zozobra, Old Man Gloom and Heatseeker, the band is still planning another compilation release on Hydrahead.

According to reports, "Brodsky just delivered a whopping four discs worth of Cave In rarities to Hydrahead –– supposedly to be whittled down for a future release"
