JellyCar Worlds (Original Soundtrack)
The main Matthew McCarthy release to highlight: elastic, catchy game music from JellyCar Worlds.
Music / apps / games / strange useful things
I make songs, software, soundtracks, iOS apps, and small experiments that usually start with curiosity and end with a little bit of electricity in them.
Now playing
The site is built around a few durable rooms: music, apps, writing, archives, and experiments. It can stay quiet when it needs to be a professional home base, then open up into band history, game soundtrack notes, support pages, blog posts, and whatever odd little tests deserve a URL.
Solo releases, indie-rock songs, video-game music, and soundtrack work including the JellyCar games.
Indie rocktronica, rock, indie pop, and synth-laced songs made with John Jacobsen.
A Boston alt-rock archive with photos, MP3s, tour journals, and the beautiful chaos of the old days.
Selected work
A few doors into the catalog: the JellyCar lineage, The Kill Screens, and Playing for Audrey. The goal is not nostalgia for its own sake. It is continuity.

The main Matthew McCarthy release to highlight: elastic, catchy game music from JellyCar Worlds.

The latest Kill Screens album: 8 songs, 31:37, released April 15, 2025.

Boston alt-rock history preserved with photos, old live recordings, and the PFA archive.

Useful corners
App Store support and marketing pages live alongside the creative work, instead of feeling like legal paperwork taped to the side of a building.
