Experimental books by Spanish/Latino writers

In the English language I like Virginia Woolf, Katherine Mansfield, a bit of Joyce (I don't like many references, so, I don't like very much Terra Nostra), William Carlos Williams, the Beatniks, Frank O'Hara and his friends... In the French language I like the surrealists, Cocteau, Blaise Cendrars, Rimbaud, Apollinaire, Exupéry, Tzara, etc.

And, yeah strange, I didn't find Borges and García Marquez soooooo interesting.
Borges uses too many references
García Marquez's surrealism is cool but most of the time I find his books boring.

Hopscotch, by Julio Cortázar?

The Memory of Fire trilogy by Eduardo Galeano

The Brief Wondrous Life of Oscar Wao by Junot Diaz

The Savage Detectives by Roberto Bolano

The Iliac Crest by Cristina Rivera-Garza but read some stories by Amparo Davilo first or you'll be lost

The most obvious overlaps with French culture might be Cortázar from Argentina (cf. >2 lilithcat:), Juan Goytisolo from Spain and Alejo Carpentier from Cuba.

I second The Savage Detectives.

I also thought of Cortázar -- I'm particularly fond of some of the stories in his collection All Fires the Fire.

Mist or Saint Manuel Bueno, Martyr by Miguel de Unamuno might work.
