Easiest way is to just email etree@archive.org and one of the admins will take it down for you. That works in both cases and will often get it taken care of within an hour or two. The LMA takes artist requests like that very seriously since without artists, there's no music.
To do it yourself, go to your item, click "Edit item", then "Item manager" and "checkout". That'll let you back in via FTP. From there you can delete whatever files you want to delete. If it's a song or two that the band doesn't want circulated, I might leave a note as to what has been deleted so someone doesn't try to come back and re-upload the complete show with the material the band wants to exclude.
