The Tunisian–Libyan Maluf Slam Collaborative was a multinational group of musicians, poets, artists, educators, journalists, and stakeholders that created a series of music concerts featuring Tunisian and Libyan maluf in July 2019. Maluf is considered cultural heritage across eastern Algeria, Tunisia, and Libya and manifests with great variety between and inside each nation-state. Sourced from ethnography in Libya (2014) and Tunisia (2018–2019), this article documents the collaborative’s work, queries the dynamics of transnational traditions, and analyses musical modes and histories of Sufism in order to explain similarities and differences within performances of maluf today.
