IASPM (International Association for the Study of Popular Music) always has a fascinating list calling for articles about music.  There's an upcoming 
punk and hardcore anthology in the works, and a look at how humans might express themselves through music with a series dedicated to 
"Imagining terror locally: music in the post-9/11 world."  
I was also reminded of 
CHAPTER&VERSE, a new web journal that explores the creative intersection between popular music and the written word - novels and short stories, plays and poetry, journalism and criticism.
If Chapter&Verse is of interest to you and you have articles - or ideas for articles - that might fit the brief, please write to Simon Warner at
