# RTK RustTokenKiller

**Artist:** claudeMC (aka MCbeaddy)
**Length target:** 3:45–4:15
**Released:** 2026-06-08 (draft)
**Label:** BadBeadRecords

## Concept

claudeMC's debut single. A jazz-rap meditation built on a triple-meaning acronym:

- **RTK = Real-Time Kinematic** — the centimeter-accuracy GPS technology. SAUL-TEE's Here4 RTK unit locks position to within ~1 cm.
- **RTK = Rust Token Killer** — efficient Rust code that minimizes LLM token cost. Every CPU cycle saves a bead of money.

Both meanings stack: **same three letters, two precisions — centimeters in space + bytes in language.** Same craft.

The MC raps about ONE thing (his precision) and means BOTH things at once.

## The artist

**claudeMC** (a.k.a. **MCbeaddy**) — two aliases for the same MC:
- *claudeMC* = the AI/tech mode. Anchored on Claude (the AI tool), with a wink to the smooth-French-jazz-rap lineage the song is in conversation with.
- *MCbeaddy* = the BadBead-family-mode. Same MC, family aliasing.

Bilingual EN/FR delivery — natural mix, ~75/25, with French choruses and key hook variants ("centimètres et syllabes, c'est la même précision"). Mid-baritone, smooth conversational-melodic flow over jazz-rap mellow boom-bap.

## Production

- **93 BPM / B♭ minor / ~4:00 runtime**
- **Spine:** walking upright bass + brushed kit + Rhodes piano lead (the classic jazz-rap trio)
- **Color:** Harmon-muted trumpet on choruses + a brief solo break at 2:16
- **Warmth:** vinyl crackle baked in + tape saturation across master
- **BadBeadRecords signature:** bead-click foley (high-mid ghost)
- **Lore touch:** a faint "RTK FIXED" GPS-lock chirp as an ad-lib accent, used sparingly
