I've started occasionally writing cast album reviews for CastAlbums.org. CastAlbums.org is a great database for cast albums, and often has reviews of albums in the database, written by a top-notch team of freelancers. It's not a regular writing job, but I'm excited to have another venue to publish my writing.
My first review was of Tamar of the River, a brilliantly written score. Check it out!
