i don't know what is yout idea of a big or small crowd...but i remember from the last year in concerts of warren suicide, x-wife or selfish cunt, there was a lot of people watching the concerts in spite off its raining cats and dogs...so i am sure that you'll find at that stage a some thousands of people...
the after hours stage is not very big...it has around 10 meters of width, for equal depth(but I am not sure)
abraços and have fun in portugal and in paredes de coura! welcome!!!
