Knife Party, the duo of Pendulum's Rob Swire and Gareth McGrillen, have released their first EP in four years.

The follow-up to 2015's 'Abandon Ship', 'Lost Souls' features four tracks and shows - in their own words - a "softer side" to their sound while still accommodating for those well-established "blood-curdling bass drops". Stream it below.

The EP was announced earlier this month. 

Last year, Pendulum dropped their debut remix album, 'The Reworks'.
