Massive Base is a Hands-Up project by Austrian producer Christoph Probst (born in Vienna) who lives in Munich.

He has been working with the music software "Ableton-Live" since 2006 and in the first few years he created a large number of innovative in-house productions in addition to some bootlegs. These were initially popular on the “MyOwnMusic” platform, but spread more and more online in the years that followed. In addition to the first official remix orders, Christoph focused on his first single "Evolution". It was released on September 10th, 2012 on the “Sonic Flash” label and made it onto the DJ Networx 50 right away! The follow-up single "Diary Of Change" in collaboration with "Buri" was in no way inferior to the debut and once again proved the Austrian's skills. This time he even found himself on the "Sunshine Live" compilation "Welcome To The Club Vol. 27" among others.
