MCIAA's debut self-released recording, a cd-r edition of 30 copies painted and wrapped in electric wire, immediately thrilled Sonic Youth and two months later the two brothers made their live debut as support to SY 1998 Italian tour. During the past years MCIAA have been invited several times to perform live at Sonic Youth European tours, Kim Gordon and Jim O'Rourke's soloist shows. In 2000 MCIAA opened the Torino BIG (International Biannual Of Young Artists) with a special audio visual performance.
In 2005 MCIAA performed at the "Music Lovers' Field Companion" festival at the Sage Gateshead in Newcastle (UK) alongside a special dual-film projections created by Roberto Opalio appositely for the occasion; at the CCA (Center of Contemporary Arts) in Glasgow with Jandek and Keiji Haino, and at the "Cosmopolis" festival at Galeria Zé dos Bois in Lisbon with Rafael Toral. The same year MCIAA toured Europe as special line-up of Jackie-O Motherfucker with founder member Tom Greenwood, and performed in Italy with Keiji Haino.
In March 2006 MCIAA took part at the K-raa-k Festival at Kustencentrum Belgie in Hasselt (Belgium).
In May 2006 they will perform at the Victoriaville Festival de Musique Actuelle (Québec, Canada).
MCIAA's international debut album was released in 2002 by Thurston Moore on his own Ecstatic Peace label; until now, several CDs and LPs have been released on Eclipse Records (USA), Very Friendly/ Cargo UK, Important Records (USA), Last Visible Dog (USA), Starlight Furniture Co.(USA), Free Porcupine Society/ Revolver USA, U-Sound Archive (USA), Time-Lag Records (USA), Gold Soundz (NOR), Rococo Records (USA), PseudoArcana (NZ), Sloow Tapes (B), Ikuisuus (FIN), Rebis (USA), A Silent Place (ITA), Root Strata (USA), Esquilo (PT), Foxglove/Digitalis Industries (USA).
In July 2004 MCIAA started on Opax Records a series of special ART-split LPs called "From the earth to the Spheres", featuring the Italian duo alongside outsider artists such as Thurston Moore, Jim O'Rourke, Jackie-O Motherfucker, Christina Carter, Thuja, Glands of External Secretion with Nels Cline, and Christian Marclay & Okkyung Lee. Each sleeve has been conceived as a proper 31x31cm Roberto Opalio's original painting on wood support. Because of the great success of the project, Very Friendly/ Cargo UK is re-issuing the whole series on CD format.
The "From the earth to the Spheres" split art series has been included in The Wire's "Avant Rock" 2004 Top 10 playlist (issue # 251, December 2004).
MCIAA's articles, interviews and extended reviews are featured on the most important international music magazines like The Wire (UK), The Sound Projector (UK), Dream Magazine (USA), Arthur Magazine (USA), The Ptolemaic Terrascope (UK), Dusted Magazine (USA), Foxy Digitalis (USA), Stylus Magazine (USA), Noiseweek (USA), Industrial (USA), Blow Up (ITA), Rumore (ITA), Il Mucchio (ITA), Gaz-Eta (PL), Indieworkshop (USA) and many more.

Both Maurizio and Roberto Opalio has soloist projects too. In 2005, together with their close collaborator Ramona Ponzini, they set up the acoustic ensemble PAINTING PETALS ON PLANET GHOST whose debut album has been released on Time-Lag Records (USA), as well as the duo called PRAXINOSCOPE.
Still in 2005 Roberto has been invited to contribute one of his original paintings for one of The Wire magazine's exclusive limited art t-shirts.
In March 2006 MCIAA have been invited from The Wire Editor-in-Chief & Publisher Tony Herrington to contribute a piece of music, plus a Polaroid by Roberto Opalio, to a volume of his art-box series entitled "Joint Multiples".
In March 2006 MCIAA have planned a new series of split ART-LPs limited to 100 copies called "Cosmic debris", which will be released on Opax Records starting from Spring 2006 on, and which will feature the Italian duo alongside artists such as Stan Brakhage's films mixed media performing ensemble Text Of Light (Lee Ranaldo, Christian Marclay, Alan Licht, William Hooker, Tim Barnes, Ulrich Krieger, Dj Olive), Californian audio visual artist and composer Steve Roden, Swedish avant-saxophonist Mats Gustafsson, avant-blues living legend Loren Mazzacane Connors from NY, and Japanese dark shaman improviser Keiji Haino.
Each record will come alongside an acrylic painting by Roberto Opalio on 30x30cm proper canvas, with a unique Polaroid installed on each piece, representing 100 different perspectives of a same subject.
