"The Reflex" is a very early and effective use of sampling, which is how they created the "re-re-re-re-flex" sound.
The original version of the song appears as the first track of their third album, Seven And The Ragged Tiger
, and doesn't contain the samples. This version runs 5:29 and wasn't deemed suitable for a single.
After the album was released in November 1983, the band heard the INXS song "Original Sin
" and became smitten with Nile Rodgers' production. The commissioned him to do a remix of "The Reflex," and working with Duran Duran synth guru Nick Rhodes, developed the famous version of the song (cut to 4:26) that was released as a single and used in the video. Sampling was so new, when he sent his remix to the band, they weren't sure what they were hearing. "We weren't sure if he was scratching," Simon Le Bon said. "Then we figured out he was repeating certain tracks but within the mix, not the whole track. It was quite innovative."
