LondonJamSession x TAM MIC DROP (20 Second Chain)

A powerful, evolving improvisation format where a musical “chain” unfolds organically — each player responding to and building on what came before.

• 2 Guitarists
• 1 Bassist
• 1 Drummer
• 1–2 Vocalists
• 1 Additional Instrument (Sax, Trumpet, Percussion, etc.)

1. All musicians are assigned a number (this determines the playing order).
2. The order, key, and available chords are written on a whiteboard opposite the stage.
3. Number 1 begins alone with a simple idea for 20 seconds — leave space.
4. Every 20 seconds, the next musician joins, layering something that complements what’s already happening.
5. Once everyone is in, the full band improvises for 5 minutes, letting the groove grow naturally.
6. No on-stage planning — just deep listening and real-time response.
7. Timer ends. Lineup rotates. A new chain begins.

It’s raw. It’s collaborative. It’s electric.

No auditions.
No pressure.
Just music.

We’ve got the amps, mics, PA system, and backline ready — bring your instrument and your passion.
