Dirty Wormz is a band. No, the tracks that have been release as "previews" for Kabosh have had nothing to do with said band. There will be (or at least that was the plan as of a few months ago) a track on the upcoming Collabos album called "Insecure" that will mark the 'debut' of Tech, Krizz & Dirty Wormz as Kabosh.
At the time it was mentioned, it was planned to be a "test" for how it would sound and see how well it was received. Since then, we've seen Kabosh receive a release date suggesting that plans are moving forward with the project, perhaps because the track has been recorded and everyone internally loved it... or they're just confident... or crossing their fingers.
