Katrine Villadsen
Ableton Live, Musikungdomsklubben, electronic Summer School, Laptop Jam
Katrine creates music and soundscapes for exhibitions and performances and has her own artistic practice as a singer / songwriter / producer under the name While We Wait, where she performs with live looping of the voice.
She develops and holds workshops and teaches courses for children, young people and adults under various musical concepts. The focus is always on the creation process - from idea to finished song and the many challenges and fun detours in between. The tools range from Ableton Live to instruments made from plastic waste.
Katrine is a co-founder of Beats By Girlz Denmark, which teaches music on computers for girls, women, transgender people and non-binaries, and works for more gender diversity in electronic music. BBG DK and Rumkraft have made several projects together.
She has released two albums with the band Kå, had her own label and is educated in philosophy and history from RUC.


Jesper 'Cigno' Svane
Sound Design, LAB TIME, Ableton Live, modular synths
Jesper 'Cigno' Svane has been DJing since Methusalem and producing music even longer. The determining keystrokes for a long career in music and sound started on a Commodore 64 and Amiga with trackers. Since then, Jesper has been on a voyage of adventurous journeys on both hardware synthesizers and samplers and especially the music program Ableton Live. Ableton began for Jesper in 2004 when Live 4 was boss of the bedrooms for producers and DJs. A hard nail sharpened for sound design, whether it comes from software, hardware, field recordings or his spaceship of a modular synth, Jesper is a true source of sound.
On a daily basis, Rumkraft has the pleasure of Jesper's always positive and infectious mood for LAB TIME - our open house sessions for the curious newcomers and weekly music club for Spaceball members and students. In addition, Jesper teaches Sound Design and Synthesis as well as Ableton Live.
Loopmasters fell over Jesper's talent for conveying sound and energy at the bass music festival Outlook / Dimensions in Croatia. Here Jesper annually taught both festival attendees and top-of-the-line DJs and performers. Since then, he has developed sample packs for Loopsmasters (check out Rectified Drum & Bass) packed with hard-hitting breakbeats, pulsating basslines and thunderous pads. Find him under the drum and bass section!
On the side, Jesper produces music for commercials and dance floors and everything in between. Currently, drum and bass is emanating from him and his partner in beats, MassF, through the duo Redline Warriors. Keep an eye on them if you are into deep bass and fast beats.
