Music Kit | Jesse Harlin, Astro Bellum

Music Kit | Jesse Harlin, Astro Bellum is a music kit created by Valve. It is a labelled music kit item rather than an agent, sticker, or case, and serves purely as an audio cosmetic within the game.

As a music kit, it replaces the default game music with its own set of tracks for the holder. Music kits are personal cosmetics that play for the equipped player rather than altering UI or weapon visuals for others.

This kit sits in the budget bracket among music kits, which means it trades in the lower end of the market and is typically easier to move than mid or premium music kits. Sellers can expect it to behave like a liquid, accessible music kit rather than a high-end collectible.

The kit was released on August 12th, 2021, as credited in the item data. That release timing anchors it to the period around that update and shapes expectations about supply and attention compared with newer or older releases.

Equipping this kit replaces the standard MVP and round transition music with Jesse Harlin's Astro Bellum tracks, giving matches a distinct audio backdrop for the holder. StatTrak variants aside, the change is personal to the player who equips the kit and alters the match atmosphere where they play.

Collectors who focus on complete music kit sets or on designer names may find value in a Valve-designed kit because of its clear provenance. As a budget-tier music kit, it can fill gaps in a collection without the premium cost attached to rarer or limited-origin kits.

You can cash this kit out through Steam-authenticated checkout for instant USD settlement. The live market price is shown on the page in the price block and reflects current buyer demand and listing activity.
