EINDBAAS, the biggest chipmusic party organizer from the Netherlands is coming to Germany with a brilliant international line-up:

cTrix [AU]: http://ctrix.net/
cTrix makes music with oldskool computers from 1977 - 1992. He then
takes them to a gig, sets everything up to run live and lets burst a
range of syles.
Phat and funky breaks, rocking chiptunes, house mixed with early 90's
vokal rave samples, buzzing oldskool sounds and early jungle D'n'B all
mixed into one show. Fun times! cTrix intergrates a Gameboy, C64,
Atari 2600, Lynx and beloved Amiga 500 & 1200 to work together, not
limited to one style or sound. While you might not know what to expect
at a show, you can expect one thing: to have a f**king awesome time!

Deadbeatblast [CA] http://www.deadbeatblast.com
Toronto based pixel pusher deadbeatblast has been crushing stages and
street corners across North America since 2007. Notorious for his
uncompromising attitude and flair onstage, his music and visuals
include a broad range of styles and platforms, often pulling
inspiration from his roots in Canada’s industrial/metal/punk scenes.
He performed nearly 100 shows to date and provided stunning video
backdrops for countless amazing chip music artists. He is the main
force behind www.bitmasters-netlabel.com

Men of Mega [NL]    http://www.menofmega.com
Men of Mega are Bart and Jasper, two Dutch guys sharing a passion for
punkrock, Long Island iced teas, and classic Nintendo soundtracks.
Using two DMGs, the NES soundchip and cut-up beats, they produce
unpretentious, hard-hitting and melodic chip music. Having only
started out late 2010, they perform as much as possible, hoping to one
day make Hip Tanaka proud.

xyce [NL]     http://www.xyce.nl
Hailing from the demoscene xyce is a happy bitpop cooperation between
powerhouses cerror and xylo. Their keygen-ish music is made with
various hardware like the Amiga, Atari 1040STe, PC and C64. While
making music on those different machines their focus is always the
same: melody and melody. It does not matter if the modules consist of
3, 4, 16 or 30 channels, melody is always key.
xyce joined forces in 2006, released three albums already and is now
more productive than ever.
