Imogen Heap has revealed on her YouTube Video Blog that she is in talks with the producers of Prince Caspian to appear on the soundtrack. She was heard on the soundtrack for “The Lion, the Witch and the Wardrobe” during the credits, with the song “I Can’t Take It In.” This is the first news we’ve heard of any soundtrack information for Prince Caspian.
Hopefully this is just the start and there will be a flood of news on the Soundtrack front. No word yet on if there will be another Inspired By soundtrack as well.
Imogen mentions Prince Caspian around the 6:20 mark.
