This is a first rate collection of sf from Langdon Jones, former literary editor of New Worlds, composer, and a very unjustly-neglected writer.
The stories range from fairly conventional ("The Great Clock") to the frankly experimental ("The Eye of the Lens"). The prose is elegant, forceful, and unfailingly eloquent. Many of the stories employ non-linear narrative techniques, but the work is always under control, and even at its most puzzling makes compelling reading.
Two stories stand out for me: "Symphony No. 6 in C Minor 'The Tragic' by Ludwig van Beethoven II" is a comic story about a less-than-great-composer who suffered from being named after the REAL Beethoven. It is slyly humorous, and if you have ever read about the lives of composers during the Romantic Period, or simply read a lot of old liner-notes on Classical recordings, it'll have you laughing.
"The Garden of Delights" is a masterful story which combines Eros, Thanatos, and Time Travel into a poignant combination that will cause you to ponder the implications for some time after. In my estimation, it stands with stories of the period from Harrison, Ballard, and Aldiss as among the best short work to come out of the New Wave.
Although the book is not large, I definitely thought it delivered the goods, and I believe it's worth your time.
There is also an interesting introduction by the author.
