After Dark has the performance direction 'Cool' which is not always what you might expect in a work for this combination. So there is a swing element as well as a bit of palm court music and a hint of the Debussy cello sonata. Interesting to say the least!
Performance duration (approx): 4'30''
Difficulty level, roughly compared to ABRSM exam grades. 0 is beginner, 9 is advanced (beyond grade 8).
