RTÉ lyric fm marks its 20th birthday in style with a powerhouse array of Irish talent in a glittering gala concert hosted by Aedín Gormley and Paul Herriott, celebrating what could well be the station's motto: the joy of music.

Watch it live from the National Concert Hall, Dublin, from 7.30pm on Wednesday, May 1st.

You'll get brilliance, drama and poetry, too, with works by titans like Mozart, Verdi, Tchaikovsky and Johan Strauss II alongside contemporary giant John Williams and no less than three world premieres by exciting young Irish composers, winners of a nationwide competition.
