These are certainly NOT concerts, but they may be of interest.

During July St Paul's Cathedral will have its main Sunday morning service with either orchestral accompaniment or to a sophisticated setting.

Sunday 6th       Coronation Mass Mozart with the City of London Sinfonia and the Cathedral Choir

Sunday 13th      Nelson Mass Haydn with the City of London Sinfonia and the Cathedral Choir

Sunday 20th      Missa Ave Regina Caelorum Victoria sung by the Cathedral Vicars Choral and featuring His Majesty’s Sagbutts and Cornetts

Sunday 27th      Mass for Double Choir Martin sung by the Vasari Singers

They always do the Nelson Mass, presumably because they are directly above the great man's mortal remains.  On occasions the preachers seems to compelled to give cod musicology rather than a proper sermon.  I can't check the preacher from the current web site.
