An interesting tidbit: Nick Warren said this is one of the three vinyls he keeps in his box at all times (the other two being The Age of Love's 'Age of Love' and Mory Kante's 'Yeke Yeke'). Here are his comments on Leftfield and this track: "Leftfield are one of my favourite bands. Their sound is so British in the way they take their influences from dub reggae to hip hop to techno and mix it all up and come out with something that wouldn't get made anywhere else. This track has all these elements. It starts with half speed reggae and comes in with all the elements of dance tracks that I love."
