With One Times One, released in late 2007, Eastgate started to issue so-called 'cupdisc' releases, that is, CDs with a running time of about 40 minutes (about the time classic vinyl albums offered back in the 70s and 80s), in most cases wrapped in a simple cardboard sleeve instead of a jewel case.
Notably, some of the later releases of this series do no longer meet the limits regarding the playing time mentioned above: they range from less than 31 minutes up to almost 78 minutes.
Particles (December 2016) was the first of a number of 'double cupdisc' releases, which consist of two CDs housed in a cardboard gatefold cover instead of a simple cardboard sleeve.
By now, the series includes the releases listed below:
* These cupdiscs came with a standard jewel case instead of a cardboard sleeve. ** These are 'double cupdisc' releases. *** These cupdiscs were released in digipacks instead of simple cardboard sleeves.
