Mezzo soprano Bethany Horak-Hallett recently made her BBC Proms debut with the Monteverdi Choir and English Baroque Soloists as alto soloist in Handel Dixit Dominus. The complete concert is available to hear again on BBC Sounds and to view on BBC Iplayer. The occasion marked Sir John Eliot Gardiner’s 60th appearance at The Proms and the programme was repeated at the Berlin Festival.
