Tatu Rönkkö & Löydetty maailma is drummer and percussionist Tatu Rönkkö's solo project, where Rönkkö plays everyday objects such as plastic bottles, bowls, empty tuna cans and plastic containers with added effects and guitar amplifiers.

Rönkkö's concerts are strongly improvisation-based, but a thread of composition still runs through each pieces with a connection, that has been described as hypnotic, playful and otherworldly. Rönkkö's music is polyrhythmic, melodic and electroacoustic. The uniqueness of Rönkkö's project has been noticed also by the mainstream media, including Yle News and Yle Olohuone program.

Rönkkö will release his solo album Löydetty maailma in early 2021.
