The Vaccines return with a brand new track taken from their upcoming Melody Calling EP. The release will comprise four new tracks, including a remix by producers John Hill and Rich Costey, and will be released on August 12 via download. Today though you can enjoy a slightly different sounding, more mellow, rather sad and reflective song titled "Everybody's Gonna Let You Down". It's definitely a more mature sound from the band. See what you make of it below.
