Deletion of Susan Addison

Comment: I incorporated the references given abovehttps://www.allmusic.com/artist/susan-addison-mn0001320806https://www.discogs.com/artist/1073043-Susan-Addisonhttps://www.theguardian.com/music/tomserviceblog/2009/nov/20/elgar-trombonehttp://news.bbc.co.uk/local/berkshire/hi/front_page/newsid_8534000/8534682.stm as well as one more from the Independent.https://www.independent.co.uk/arts-entertainment/classical/news/great-composer-shame-he-couldnt-play-1824125.html I think she passes  for significant discussion in secondary sources that are independent of the subject. She is known for her research in historical trombones (as indicated by the discussion in the articles above about her research work with Edward Elgar's trombone) and was awarded an Hon.RAM from the Royal Academy of Music in 2002, which may not quite satisfy  but I think it does add a little bit to her notability. I also added several references to verify each piece of information in the article. However, the most strong reason I believe the article passes the notability test is due to  because the subject "is a musician who has been a reasonably prominent member of two or more independently notable ensembles." She was a founding member and principle trombone player for the Orchestra of the Age of Enlightenment, and a founding member and 25-year player of His Majestys Sagbutts & Cornetts
