04 What's new



Polytope Booking is very happy to officially seal the deal with Anne Karolczak aka Pretty Pink. The female DJ, risen from the deep & dark woods of the Harz in Germany, made a substantial way through the steaming and raging international club scene to manifest her belief in the very finest tunes of Nu Disco, Deep – and the most unique secret selection of House. Pretty Pink by now is a fairly well known artist within Europe. Her edit of Daft Punks Get Lucky truly turned into a underground hit and has been played by famous DJ’s around the world.
With no doubt, she incorporated all projects ready to catch fire and go viral since she’s very active on all social media channels. „My background in design studies helped me to get my style pointed in the right direction“.

“Bad Ideas make the best memories, even if you don’t remember them…” True to that motto, Alle Farben is putting out his second single from his latest Long Player “Music Is My Best Friend”. After the first hit single “Please Tell Rosie” (feat. YOUNOTUS), which has already achieved Gold status in Germany and Austria, this time the focus is shifted from Rosie onto the “bad ideas” people may have in life, which usually turn out to be the most memorable. Musically, the Kreuzberg resident adds more colorful elements to his wide palette of ideas this time out. This time beats are combined with chilled guitar fills and vocal hooks from Nashville resident Chris Gelbuda, who’s vocal crosses the track over into potential pop-hit territory.

June 3rd Alle Farben releases his new album‚ Music is my best friend‘. With the recently published singles ‚Please tell Rosie‘ and‚ Re member Yesterday‘, the Kreuzberger pops two promising songs which currently charted the #22 single charts. The LP will be his second studio album. After plenty of live gigs in March and April, Alle Farben can be seen this summer at festivals such as Lollapalooza in Chicago or the Frequen- cy in St. Pölten. The DJ has been touring all over the world and in 2014 he released his debut album ‚Synesthesia‘. The lead single ‚She Moves‘ cracked the top 15 European airplay charts, reported in an instant Gold status, and is currently slightly ahead platinum. Likewise the song ‚Super Girl‘, a collaboration with YOUNOTUS and Anna Naklab, went straight platinum. We are very happy and excited to see what’s next

Berlin/Mumbai, June 24th 2016 Polytope Booking establishes a branch in India’s 12 million metropolis and is now represented internationally. Under the umbrella of Guesstimate GmbH, the Berlin booking agency starts a counterpart in Mumbai. Polytope is extending their international roster next to artists like Alle Farben, YOUNOTUS, Pretty Pink & Parra for Cuva. From the years of work by Polytope Booking, the Asian market was extrapolated to Berlin booking. Therefore, it was only logical for their internationally oriented network to not only have a local partner but also an overseas branch in Mumbai. From now on, Aneesha Kotwani takes over the booking in Mumbai.
