This box comes at a bargain price and it contains the cvasi-complete organ works of Bach (excepting Neumeister collection). I consider it is one of the best modern recordings existing nowadays. The Trio Sonatas, the concerts and the Eighteen Chorales are wonderful and very original - to say the truth, Preston has a new, modern vision on Bach. The organs chosen for these recordings are among the best ones, with a so pleasant sound! DG engineers made a good job, as the Organ is one of the most difficult instrument to be recorded. They deserve all our esteem! Among my other complete organ recordings, Mr. Simon Preston's set is one of the best existing in my collection and I listen often to it or to Marie-Calire Alain' third recording from Erato (another gem!).
