We found this web site and it is just way over the top in insanity and just totally cool! Benoît Maubrey has been making these crazy outfits that have amps, pedals and instruments built into them. They then do these street performances or crazy recordings. You must goto the site and check out some of the concepts during the years.
A MUST !!

Here is his bio and History.......

BIO:Since 1983 Benoît Maubrey and his Berlin-based AUDIO GRUPPE have been buiding electro-acoustic clothing and suits. These are clothes equipped with loudspeakers, amplifiers, and 257 K samplers that enable them to react directly with their environment by recording live sounds, voices , or instruments in their proximity , and amplifying them as a mobile and multi-acoustic performance. Additionnally they also wear radio receivers, contact microphones, light sensors and electronic looping devices in order to produce, mix, and multiply their own sounds and compose these as an environmental concert. The performers also use rechargeable batteries and/or solar cells which ensures them complete mobility both indoors and outdoors.

A brief history:
1982 -- creation of the first AUDIO JACKETS, second hand clothing onto which loudspeakers have been sewn. These first prototypes are equipped with portable cassette players and 10-watt amplifiers. They play prerecorded cassettes.

1985 -- development of the first Audio Uniform for the Bundesgartenschau 85: the AUDIO HERD is a custom-built series of 7 two-piece suits made of synthetic animal skin material. Inside the clothes the performers wear loudspeaker corsets. On the back of the jackets is a visible 30-watt amplifier. The Audio Herd functions like a real animal herd, it wanders through the landscape of the Bundes Garden Show in Berlin. The sound artists Hans Peter Kuhn made a series of animal-noise cassettes that the performers play as they wander around.

1986-- the AUDIO STEELWORKERS is created for the Ars Electronica festival in Linz, Austria. This is a series of 10 electro-acoustic uniforms based on the fireproof aprons and clothes worn by the workers in the local steelmills. Hans Peter Kuhn makes a series of audio cassettes based on the sounds from the steel mills.

1987 -- the GUITAR MONKEYS are a group of noise musicians that wear black leather jackets equipped with 30-watt amplifiers and loudspeakers. This band plays guitars that are found at the flea markets in Berlin. These guitars are amplified via Piezo microphones that are then plugged into their electronic clothes.

1988 -- the AUDIO SUBWAY CONTROLLERS wore authentic subway controller uniforms into which amplifiers and loudspeakers were installed. They played back the original voice sounds from the Berlin subway attendants (All aboard, Please!, etc..) while unofficially patrolling the subways.

1988-- the AUDIO CYCLISTS was built for the Festival des Arts Electroniques in the city of Rennes. This is a group of professional cyclists that wear Audio Tricots and play back the voice of Bernard Hinault (5-time winner of the Tour de France) while officially racing through the streets of Rennes.

1989 to 1996 -- the AUDIO BALLERINAS was created for the Festival Les Arts au Soleil (L'Aeronef, Lille., France). In this case a new Audio Uniform , based on the design of a ballerinas' tutu, was built using solar cells to power the electronics. At the same time digital-memories (257 K samplers) were used instead of cassette players: this permits the performers to record live sounds from around them. Electronic looping devices, light sensors, radio wave receivers are also included on the plexiglas surfaces of the tutus: in the end the Audio Ballerinas were able to create an entire spectrum of sounds via their clothing.

1993 -- AUDIO GUARDS during the ULTIMA Festival in Oslo: 7 Berlin dancers wearing electroacoustic imitations of the official Royal Swedish Guards' uniforms. Choreography: Sygun Schenk. Sound: audio umbrellas and audio shoes.

1994 -- in cooperation with the Theatre zum Westlichen Staathirschen an audio theatre piece was created -- AUDIO DRAMA . In this situation different Audio Characters were created and interacted with each other in a 45-minute black-box theatre situation. Among other memorable electronic characters: FEEDBACK FRED -- a tragic-heroic personality equipped with an oversized loudspeaker box on his back, audio face mask, and microphone who is continually battling the effects of his portable feedback.

1996 -- based on the new electronic capabilities of the Audio Ballerinas the ELECTRONIC GUYS are created. These gentlemen wear evening jackets with tails and are equipped --depending on the situation with portable samplers, electric guitars, microphones, receivers, and light sensors. They complement the Audio Ballerinas in their indoor theatre pieces.

1996 -- the CELLULAR BUDDIES were created for the SONAMBIENTE Sound Art Festival at the Academy of the Arts in Berlin. In this project 5 museum guards carrying electro-acoustic briefcases were equipped with cellular telephones and amplification systems that allowed anyone to call them up and talk out loud through them during exhibition hours.
Complementary to this project: since 1982 Benoit Maubrey has created a number of "ELECTRONIC SPEAKER'S CORNERS" . Essentially these are public electroacoustic sculptures that anyone can "call up" and talk through.

1997 -- AUDIO GEISHAS were created for the opening of NTT- InterCommunication Center in Tokyo. In cooperation with the Japanese performance group "Venus Show" -- 4 Japanese performance artists were equipped with AUDIO KIMONOS complete with guitar amplifiers, digital memories, solar powered radio receivers, and microphones. Performances of the AUDIO GEISHAS and AUDIO BALLERINAS were held in different public spaces in Tokyo ( Tokyo Opera City Tower, Spiral Hall, Akihabara "Electric City", the Milk disco) and in front of Yokohama Museum of Art.
