What roles did Mark Bell and Matmos play on the new album?
 
 
matmos were with me in the beginnig and sort of saw it coming with me being obsessed with spike jones and bodenstandig 2000 , choirs and vocal only stuff . they were very graceful and then drew kept introducing me to more vocal stuff i had never heard . they did create fruit machine noises for "who is it " which i later imitated with my voice . mark bell came later into it he´s funny . i e-mailed him "where is the line " and like a year later he e-mailed me a little idea for it . then when i was mixing in london , i hadn´t been in england for ages then , he would turn up at the studio a lot and ended up rescuing "triumph of the heart" for me . that was the last song and had been the hardest one to get right. he was around when rahzel sang his beat in "where is the line " so he helped us editing it . so overall i did most myself but got like 5 percent a little help from friends.
