Music / apps / games / strange useful things

Matthew McCarthy

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

A personal site that behaves like a studio.

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.

Selected work

Albums, games, archives.

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.

Useful corners

Apps get proper homes too.

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