HELIOS performs several concerts a year, mainly in London and the south-east, and has made two successful visits to the Basque region of southern France. We have tackled a wide variety of a cappella music; our repertoire extends from mediaeval to contemporary, involving specialist instrumental ensembles as needed. Our previous performance highlights include Carl Rütti’s Missa Angelorum, Rachmaninov’s Vespers, Monteverdi's Vespro della Beata Vergine of 1610, Britten’s cantata Saint Nicolas, and Stephen Jackson’s challenging Beatles arrangements Let It Be.

Elsewhere on the site you can see a full list of past events and hear some excerpts from live recordings, or you can see what's coming soon.

We hope to expand our repertoire into opera and jazz. Among other areas we hope to expand our repertoire into opera and jazz. Read more about our future plans and more concerts over the next year.
