• DJ Fresh (real name Daniel Stein) is a British-based drum & bass producer. He teamed up with Kosheen vocalist Sian Evans for this song, which was released on July 3, 2011 as a digital download.
• Stein told the story of the song in an interview with Ministry of Sound: "I started 'Louder' at the end of last year, it began as an instrumental though it was always supposed to be a song with a vocal. I played it out at a festival in Belgium and the crowd went nuts! Sian Evans (who I knew from her days as frontwoman of Kosheen) and I had been talking about working on something together for a while and it seemed like the perfect track. I had a muffled recording of the chorus (with slightly different words), and I'd excitedly got out of bed to sing into my phone at about 3 o'clock in the morning one night. When Sian started scatting around it it worked perfectly, we changed a few words, notes etc and then wrote the verses, the whole song was written like that in just one night!"
• The song was used as part of a Lucozade Lite advertising campaign in the UK and Ireland. Stein explained to Ministry of Sound: "'Louder' came to be used in the Lucozade Sport Lite advert after the Lucozade team saw the video for 'Gold Dust' and heard my last single 'Lassitude'; they then approached me and Ben Newman, the video director of 'Gold Dust' to work together on the 'Louder' video and Lucozade ad. I think that even I have managed to catch the advert on TV - I hardly ever get time to watch TV so that's actually pretty amazing!!"
• According to the UK's Official Charts website, the song was the UK's first dubstep #1 single.
