::: There must be a source for red link articles. 
 ::: Since most music artist articles are poorly or non sourced fan articles the Wikipedia article for that act must have reliable sourcing that specifically mentions alternative rock or one of its sub-genres.   
 ::: If you implement these standards be prepared that nearly if not every day editors who are for the most part non users will add items that violate them. That is how it is with the synthpop and the New Wave lists and those categories are much smaller then alternative rock. Which is why I don't edit here. 
 ::: Good luck!!!
