What is the song in the AMC commercial on Comcast OnDemand?

I am looking for the name of and the artist of the song that plays
during the commercial breaks of AMC shows OnDemand. It advertizes up
and coming seasons for the shows Breaking Bad, Mad Men and The Walking
Dead. The song sounds like a combination of "Creep" by Radiohead and
the "28 Weeks Later" theme song.
