Invenio is an innovative large ensemble of improvising and contemporary singers, experimenting with the typical vocal group/choral form through conceptual composition, extended vocal technique, fluid improvising, choreographed movement and inventive performance. The singers of Invenio are selected from a pool of exciting contemporary singers who are all active performers, teachers and composers on the Melbourne scene.
Singer/composer Gian Slater formed Invenio in March 2010 to perform her large-work commission piece, Gone, without saying for the Melbourne Jazz Fringe Festival. The performance received rave reviews and a standing ovation and from this auspicious beginning, Invenio was born.  Since then, Invenio have performed Gone, without saying at the Sydney Opera House Studio for the prestigious Freedman Fellowship Awards, Dancehouse Theatre, La Mama Musica, Canberra Street Theatre and Colbourne Avenue music series.
Invenio premiered Slater’s second large work, Us and Others, in 2011. The piece, composed for 18 singers and 4 percussionists from SPEAK Percussion (led by Eugene Ughetti) was performed at the Malthouse Theatre to sell-out audiences. Slater then composed two new works for Invenio’s 2012 sell-out performances at The Northcote Town Hall. Self/Echo, composed for five voices and Clarion/Whisper, for the full ensemble, received a 5 star review in The Age.
In 2011, Invenio began their collaboration with esteemed NY based Pianist/Composer, Barney McAll, performing their work Graft at Bennett’s Lane Jazz Club and the Wangaratta Jazz Festival. Graft was recorded and released on Jazzhead label in May 2012.
Invenio’s longstanding collaboration with treasured singer/songwriter, Lior began when they featured in his Speigeltent season over three sold-out nights in 2011 as well as the Melbourne Zoo Twilight concerts in 2012. In March 2013, they performed with Lior as part of the Speigeltent season once again over 4 sold out nights, although this time they were his accompaniment for the whole show.  They performed alongside Lior at the 2013 Apra Music Awards, closing the night with a tribute to ‘The Seekers’.
Invenio also featured in the Melbourne Arts Festival’s Notes from the Hard and Beyond at Sidney Myer Music Bowl, with the Black Arm Band, Ricki Lee Jones, Mavis Staples, Archie Roach and Joss Stone.
Invenio released their debut album, Gone, without saying, on the Listen/Hear Collective Label in late 2011 and their second album Clarion/Whisper in March 2014.
