What is "white knuckle ride"

n. (alternative spelling of white-knuckle ride English)

"White Knuckle Ride" is the first single from British alternative group Jamiroquai's studio album, Rock Dust Light Star. The single was released via Digital Download on 31 October 2010, with a Limited Edition Vinyl release due to appear on 1 January 2011. The song was written by band frontman Jay Kay and Matt Johnson. It is the band's first record to be released under Mercury Records.

The band's official website originally announced that the single would be released on 11 October. The band describe "White Knuckle Ride" as "a hi-octane retrospective on Jay's career experiences - a cautionary tale equally applicable to anyone's life in these pressure cooker times." It appears that the Jamiroquai logo typeface has been stretched vertically for this release. The video for the single was made available on the group's YouTube account on 25 September.
