Balls is the 18th studio album by the American rock duo Sparks, released in 2000. Balls was a continuation of the techno-pop style that the duo had first explored on 1994's Gratuitous Sax & Senseless Violins, but employed harder, more uptempo beats, as well as a direct, aggressive approach derived from acts such as The Prodigy. The album was packaged in a translucent jewel case that came in a variety of colors, with a reflective die-cut silver slipcase. "It's a Knockoff" was recorded for the movie Knock Off starring Jean-Claude Van Damme, directed by the acclaimed Hong Kong–based producer–director Tsui Hark. It is featured over the closing credits. Whilst critical reception of Balls was moderately positive, it was not a success in terms of chart performance and failed to match the performance of Gratuitous Sax & Senseless Violins. It did not chart in Germany, the UK, or the US. "More than a Sex Machine", "The Calm Before the Storm", and "The Angels" were released as singles but did not pick up any significant sales or radio play. The duo had already written a follow-up to Balls in a similar vein.
