Four recordings of chamber-oriented improvisation by Serbian violinist Szilárd Mezei in a trio with bassist Zoltán Csányi, a frequent collaborator of Mezei, and Catalonian percussionist Vasco Trilla, performing in 2021 at KC Lab in Novi Sad, at RCA Magyarkanizsa in Serbia, at Samo Pivo in Subotica, Serbia and at Korzó Zeneház in Szeged, Hungary.

Four double basses and a tuba, recorded in an arc to elucidate the sound of each instrumentalist, in Serbian improviser and composer Szilárd Mezei's deep-rooted Tubass Quintet, Mezei taking one of the double bass roles in place of his typical viola & violin work, as his compositions bring the deep instruments into both foundational and melodic territory.
