The artist collective MOSES & TAPS™, which has been cooperating since

2007, is well- known for its graffiti on trains and walls all over the world. The

collective occurs under different names as for example TOPSPRAYERä or

ERNI & BERTä, in order to preserve their anonymity. Meanwhile, it is no longer

clear how many writers work under these pseudonyms. The artistic careers

of MOSES & TAPS™ began independently of each other in 1994. Similar

thoughts and opinions about graffiti led the two sprayers 2007 together.

The painting process is of importance for the collective. The painting process

should always be a performance in which the body is used, so that the pieces

get a kind of liveliness.
