Lomax The Hound of Music is a short-lived show that was produced by Sirius Thinking LTD. (the same company who created Between The Lions). Just like its more-popular sister show, Lomax brings together puppets, humans, and animation, but instead of teaching kids about reading, it instead teaches kids about music.
This show follows the adventures of Lomax (named after American ethnomusicologist Alan Lomax), a good-natured, melody-obsessed puppet hound dog, his fluffy cat sidekick, Delta, and their human companion, Amy, on a tune-filled train ride aboard the Melody Hound Express crisscrossing the musical landscape of the United States of America. With the help - and full participation - of real kids on the train, on location, Lomax and his friends track down the wonderful songs in different music genres and music styles that form the heart of the nation’s most diverse musical heritage on the planet earth. Also aboard are Louise and Clark, a pair of adventurous fleas who have hitched a fun-filled ride on Lomax.
The show aired from October 6 - December 29, 2008. It got cancelled due to production issues, but reruns continue to air until 2010. It's possible the characters from the show will join the Between The Lions family in its sister show's upcoming reboot.
There was a website on PBSKids.org that was launched in 2008, but was closed down in 2016 (along with older PBS Kids shows including its sister show Between The Lions). It's possible to access it on archive.org, but since the website runs with flash, it'll never work, which means that the other pages and games are completely lost. Though Sirius Thinking LTD. might put the show's games on its website.
