Alternative Light Source

Alternative Light Source is the third album by the English electronic group Leftfield, released on 8 June 2015. It is the first new material following the band's 1999 album Rhythm and Stealth. It is also the first Leftfield album without Paul Daley, as well as the first since the band's return in 2010.

On 1 June 2015, the album premiere was streamed live on Leftfield's website, coupled with live tweeting about it on the band's Twitter feed with hashtag #leftfieldstream.

Critical reception
Nick Annan of Clash said "Alternative Light Source is a worthy successor to Rhythm & Stealth, not as sparse or hard hitting but brimming with energy, ideas and familiar Leftfield diaphragm-rattling bass." Mojo's Stephen Worthy commented that Neil Barnes "meets the challenge" of releasing a followup to Leftfield's previous albums that went platinum, and said that the album, "...aided by a clutch of judicious guest appearances, balances crowd-pleasing festival epics, intense techy workouts and bubbling synth lullabies."
