Stalking Horse is the solo project of Wu, formed after the break-up of This Et Al in late 2008. The act is based in the United Kingdom. Recording begins in August 2009 on the East Coast of England, with producer James Kenosha at The Lodge in Bridlington.

The project releases an album titled Specters and the Too Pure single Heathen Head, Howling Heart. Its music uses a range of instruments, including Chinese guitars, mandolins, pianos and ukuleles, and moves between the more up-tempo feel of Heathen Head, Howling Heart and the more fragmented tone of Off Auto.

Stalking Horse is described as drawing on elements associated with Warp Records and Thom Yorke, while maintaining a distinct sound. The music is presented as atmospheric and escapist, with an emphasis on songwriting that balances creativity and restraint.
