Back and Forth Music Festival

Back and Forth is a festival for modern music (pop, rock, folk etc.) with acoustic instruments. It lasts 4 days and takes place in Berlin. The concept follows the 3 data which are rearrangement, intimacy and interaction. The interaction mainly refers to the logo which is flexible. It adapts to the music which is played live. It visualizes the different frequencies, speeds and volumes. So there is not just 1 logo, there are uncountable possibilities.
