We have be more concerned with such an ontological alchemy, easily stating 
real things as unreal, and unreal entities as the real.
For an eventless world is a world without change, and a world without change 
is a world without time, with all the ensuing consequences (of imortality 
and eternity :).
No event, no change; no change, no time; no time, no human history, memory 
and experience, i.e., no both human life and mental life.
Both an eventless world of objects, and an objectless world of events are 
poor constructs. It's like constructing an eventless web of objects, and an 
objectless web of events. When somebody doubts if events exists, if there 
are any events, he actually doubts if anything in the world happens at all: 
the Olympics, festivities, sporting events, his birth, dates and marriage, 
and possible death.
Re. literature on Events. It is vast, 
http://books.google.com/books?q=Events. I recommend to start from an 
anthology on Event, studying its ontology, semantic, logics and NL 
descriptions, very useful to read for all the semwebers, 
http://books.google.com/books?id=PZ7WAAAAMAAJ&q=Events&dq=Events. The book 
consists of five Parts: Events in Semantics; The Nature of Events; Identity 
and Individuation; Cause, Space, and Time; Events and Processes.
An integrated ontological account of change (and event) is given in the 
Reality book, 
Have also to mention, there is an emerging multi-billion business, called 
Event Management Industry: dealing with all sorts of international social 
events, festivals, ceremonies, sporting events, mass media events, summit 
meeting of all sorts and kinds.
Apropos, there are many festivals, arts, film, literary, music, religious, 
science, but an Internet/Web Festival :).
