In the car on the way from Honfleur to Dunkerque:
Bruckner - Symphony No.7 (complete this time)
Smetana - String Quartets
Shostakovich - String Quartet No.8
Shostakovich - Symphony No.8
Then, while waiting for the ferry at Dunkerque:
Shostakovich - Symphony No.10
Driving back home from Dover:
Janacek - String Quartets
Philip Glass - Excerpts from Akhnaten, Company, Violin Concerto
Bartok - String Quartets 1, 3, and 5
Messaien - L'Ascension
Fairly loud Shostakovich maybe not the obvious choice for a ferry queue, but it was actually rather excellent, and provided wonderful accompaniment for a while reading in the car.
Philip Glass not the obvious choice for driving home late at night either, but I didn't feel sleepy, so it was fine!
