Loved High rise, Concrete island, Empire of the sun. Also make sure to read this: https://www.jgballard.ca/uncollected_work/what_i_believe.htm...

I really enjoyed some of his later books too. Cocaine Nights and Super Cannes are great.

Like a lot of his books they seem simple until you dig into them. They fry my brain a bit but that’s surrealism for you.

Will Self has some good writing about Ballard.
