A very nice introduction to Locality-Sensitive Hashing theory and some details regarding how can the lower-bounds for LSH be beaten (spoiler, use data-dependent hashing) by Alex Andoni.

The nice thing is that there has been some practical algorithms for LSH being proposed using data-dependent partitioning (self promotion time) and this latest work by Andoni has shown a very interesting theoretical link with this approach and data independent LSH.
