Kaleidoscope Chamber Collective was dreamed up in 2017 by Tom Poster and Elena Urioste. Its primary aim is to bring wonderful musicians together to perform in new and varied combinations, but with a specific and ardent commitment to celebrating diversity of all forms. 


Like many musicians, Tom and Elena spend a lot of time worrying about the world - about inequality, prejudice, violence, bullying, divisive rhetoric. Chamber music has an extraordinary power to bring people together: it unites musicians as equals, allowing them to learn from and be inspired by each other, and draws listeners in to its intimate, transportive world.


Through exploration of great repertoire both familiar and unexpected, played with passionate commitment by a diverse and brilliant team, Kaleidoscope Chamber Collective hopes also to inspire and educate younger generations (and older ones too!) in the joys of chamber music, and hopefully bring a bit of happiness and cohesion to our currently rather fractured-seeming world.

Forthcoming engagements include residencies at Wigmore Hall and Kettle's Yard, Cambridge; and festival appearances in Beaminster, Cheltenham and Ischia.

Tom composed music through his childhood and teenage years, most ambitiously writing two chamber operas (based on short stories of Oscar Wilde) before his 14th birthday. Following a compositional hiatus in his twenties as his performing career took off (though he continued to make arrangements of Great American Songbook favourites), he has recently returned to writing music.

Recent commissions include two pieces for Alison Balsom, Turn to the Watery World! (a piece about unusual sea creatures which includes perhaps the first musical depiction of a blobfish) and The Thoughts of Dr May (inspired by Queen guitarist Brian May, and recorded for Warner Classics); and The Depraved Appetite of Tarrare the Freak, a chamber opera for Wattle & Daub, which enjoyed a critically acclaimed three-week run at Wilton’s Music Hall in 2017 - please see clip for a taster.

In April 2019, Tom will premiere his short song cycle, The Turning Year, with Matthew Rose at Wigmore Hall, and his reworking of songs by Cole Porter and Kurt Weill was premiered by Claire Booth and Alisdair Hogarth at the 2018 Lammermuir Festival and broadcast on BBC Radio 3. A full-length musical for Wattle & Daub, inspired by the extraordinary life of Dr James Barry, is currently in progress.
