The album was originally slated to be released in North America on March 14, 2006, but was canceled just days before its release. This is likely due to Prince not wanting competition with his new 3121, scheduled to be released only one week later. However, promo copies of the album had already been sent to some retailers and were sold before the album's recall. A second release date of May 22 was proposed, but was again canceled and the album's future was unknown for a time. Three months later, it was officially released on August 22, 2006 to generally positive reviews.
The album was certified Gold and sold over 650,000 to date. In 2004 British girl-band Girls Aloud recorded "You Freak Me Out" for the film and was intended to be added to the soundtrack, however it was decided not to add it to the album, but was included on the re-release of the band's debut album, Sound of the Underground (2004).
A gear or cogwheel is a rotatingmachine part having cut teeth, or cogs, which mesh with another toothed part to transmit torque, in most cases with teeth on the one gear being of identical shape, and often also with that shape on the other gear. Two or more gears working in a sequence (train) are called a gear train or, in many cases, a transmission; such gear arrangements can produce a mechanical advantage through a gear ratio and thus may be considered a simple machine. Geared devices can change the speed, torque, and direction of a power source. The most common situation is for a gear to mesh with another gear; however, a gear can also mesh with a linear toothed part, called a rack, thereby producing translation instead of rotation.
The gears in a transmission are analogous to the wheels in a crossed belt pulley system. An advantage of gears is that the teeth of a gear prevent slippage.
When two gears mesh, and one gear is bigger than the other (even though the size of the teeth must match), a mechanical advantage is produced, with the rotational speeds and the torques of the two gears differing in an inverse relationship.
Gear is a Linsnarian (named for Joseph Michael Linsner?), a race composed of organic machinery beneath humanoid shells. The Blackstar Juvenile Correctional Facility captured him for use in maintaining their systems. For quite some time, he pretended to be servile, while programming some of his machinery to disable the systems keeping the inmates contained and powerless upon his deactivation. On the arrival of the Legionnaire Sensor on the station, he was convinced by her to move prematurely, and was severely damaged in the process, activating his failsafes.
However, Brainiac 5 successfully repaired him, and Gear remained on the Legion Outpost space station until most of the Legion was lost in a rift and the team was forcefully disbanded as a result. R.J. Brande then made contact with many of the remaining Legionnaires, including Gear, and put together a plan to construct a "Legion World" - an artificial planetoid to house a revived and expanded team, which Gear and Invisible Kid designed and helped to construct.
