Launching on 9 January at the ZK/U, the CTM/transmediale Vorspiel programme returns for a fourth year in a row, uniting over 30 Berlin venues and initiatives in a city-wide programme running until end of January.

On Thursday 29 January members of the ICAS - International Cities for Advanced Sound network will be holding a speed-dating session where artists, professionals and interested members of the public can present their work/research, and learn more about the network's festivals and events. The event is by registration only!

Opening Friday 23 January, the Un Tune exhibition explores the possibilities and limits of music and sound, and their interference with contemporary art. In addition to works by Emptyset, Anita Ackermann, Anke Eckardt, Nik Nowak and more, the exhibition features  daily performative elements as part of Claire Tolan's "Always There for You" and Derek Holzer's "Delilah Too" installations.

Lectures and roundtables ranging from archaeoacoustics to alien agency, public presentations within the MusicMakers Hacklab, artist talks, networking activities, and more.

On Wednesday, 28 January at the Kunstquartier Bethanien's Studio 1, antiquity specialist Iegor Reznikoff will perform selections of Early Gregorian chant and his own composition, "Cantata Grand Magnificat", for a very special benefit concert and the festival's only exclusively acoustic programme. The performance features Reznikoff's exploration (with his unamplified voice) of the resonant properties of the space, which served as a chapel when the Kunstquartier was still used as a hospital.

Continuing its mission to support the city's emerging sounds, Berlin Current launches into its third consecutive year with performances by Lumisokea, Lotic, and KABLAM at Malmö's Intonal Festival in April, as well as Lumisokea and Dasha Rush's live AV project "Antarctic Takt" with Stanislav Glazov at MUTEK Montreal in May. More events as well as 2015 supported artists will be announced soon!

As one of the best informed commentators of Berlin’s music and arts scene, and as a dear friend, Meike has supported the activities of CTM from the very beginning – and beyond. She died this past Saturday. An obituary.

For sixteen years, Sunn O))) have been challenging the way we think about music. In that relatively brief time, core members Stephen O'Malley and Greg Anderson have forged connections between the worlds of Metal, Drone, Contemporary Composition, Jazz and Minimalism with startling results while remaining true to the eternal principles of volume, density and weight. On August 9, 2015 they return to Berlin for the first time since their glorious show at CTM 2013. Tickets are on sale now.
