Mammatus

About

Mammatus is a Czech-Slovak jazz project led by Slovak multi-instrumentalist, composer and vocalist Sisa Feher. The band plays riff-driven alternative jazz with experimental leanings, addressing contemporary social and environmental themes through both music and lyrics. The project is tied to the album of the same name, released in November 2024 on Slnko Records, and follows Feher's previous record KHI (2021). The ensemble features leading Czech and Slovak musicians: Vojtěch Procházka (keys, synths), Oskar Török (trumpet), Štěpán Janoušek (trombone), Miloš Klápště (double bass) and Marek Urbánek (drums).
