Morley College Choir was founded by Gustav Holst, during the period he was teaching music at Morley College. The choir was led for many years by Michael Tippett, who conducted the ensemble for the first-ever recording of Thomas Tallis' Spem in Alium, and premiered a number of Tippett's works, including A Child of Our Time in March 1944.
Michael Tippett conducted the first ever recording of a Thomas Tallis work.
The statement belongs in the category because the excerpt states that Michael Tippett conducted the first recording of Thomas Tallis' Spem in Alium, but it doesn't specify if this is the first Thomas Tallis work to ever be recorded. The model may have been confused by the wording in the article.
