This transcription, by the excellent Swiss organist Benjamin Righetti, has something special : it's baroque music (the Dido's death at the end of Purcell's Dido and Aeneas), but the transcription is specified "for a big symphonic organ" and the style is very symphonic.
So, this surely doesn't sound "by the book" ! But, IMHO, I repeat IMHO, it captures the drama and emotion of this scene better than the diverse baroque style transcriptions I could try and found disappointing. But everyone may - of course - have the opposite opinion :-)
