Dynamic page with comments

You probably can hack comments in somehow, but don’t. Create a custom post type for your musicians using register_post_type() and including “comments” support.

You can then create post type templates to customize the display:

  • archive-{post_type}.php — for archives
  • single-{post_type}.php — and for single posts

Comments should now work properly without your having to hack around with them.
