An Omen EP

An Omen EP (stylized as An omen EP_) was the second extended play release by American post-industrial group How to Destroy Angels, released November 13, 2012. Produced by Nine Inch Nails frontman Trent Reznor, his wife Mariqueen Maandig and longtime collaborator Atticus Ross, the EP contained various tracks later issued on their 2013 debut album, Welcome Oblivion. It focused on Maandig's vocal style, with a lighter tone than its predecessor.

The full EP was released for streaming purposes on November 8, 2012 at The Hype Machine and the band's official SoundCloud channel, five days before the official release date, then was released in digital and vinyl formats afterwards. As with many of Reznor's official releases, it was designated with a unique name and number: An omen EP_ is "SIGIL 03".

The release was announced by Reznor in 2011, and initially slated for a November 2011 street date. However, due to Reznor's dissatisfaction with the output, it was put on hold until he felt it was up to standard, taking it on what he referred to as a "Mulholland Test Drive". The title was announced on September 22, 2012 as An Omen EP.

This was Reznor's first musical release (from either Nine Inch Nails or How to Destroy Angels) on Columbia Records, and his first non-independent release since Nine Inch Nails' Year Zero Remixed, which was released on Interscope.
