It's an album that went on sale at DCA this weekend with the opening of Cars Land. The CD has various tracks that can be heard in the background at Cars Land, including a ride-through of Radiator Springs Racers, a Spanish version of "Low Rider" that can be heard in Ramon's House of Body Art, and 6 of Mater's calls from Mater's Junkyard Jamboree (!).
I haven't had a chance to listed to the CD yet, but seeing as it's been almost 4 years since we've seen a DLR official album, it's a welcome addition.
