On 20 and 21 September 2013, Level 42 (joined by an expanded brass section), performed three new songs at London's Indigo O2 Arena – "Where's Yo' Head At", "Too Much Time", and "Sirens". All of these appeared on the band's first new release for seven years, the six-song studio EP "Sirens" (released on 31 October 2013, and the first output from the band's new self-owned label Level 42 Records). Mixed by the American DJ John Morales, the EP also contained "Mind On You", "My Independence Day" and "Build Myself a Rocket" (with King's daughter Marlee providing the backing vocals on the last of these tracks). Musically, it built on the production approach of "Retroglide" while allying the band with contemporary developments in R&B and dance electronica.
