Untested code....

import os, fnmatch
for each_file in fnmatch.filter(os.listdir(path), '*.mp3'):
  id3r = id3reader.Reader(each_file)
  if id3r.getValue('performer') and id3r.getValue('title'):
    output = open('output.html','ab')
    output.write('<p>%s - %s</p>\n' % (id3r.getValue('performer'),
id3r.getValue('title')) )
    output.close()
