Stephan Mathieu's »FrequencyLib« was originally released in 2001 on Mille Plateaux's Ritornell sublabel. A quintessential document of the late 1990s/early 2000s Pismo PowerBook era of digitally manipulated audio, »FrequencyLib« is an adept meditation on the entropic possibilities inherent in popular music. Included with this reissue is the complementary »Sad Mac Studies« EP - first issued in a run of 100 on Robert Meijer's boutique En/Of label. Exploring similar themes/processes as FrequencyLib, »Sad Mac Studies« reimagines and deconstructs the sonic world of Sesame Street.

Umeboshi is A new record label run by former Root Strata co-principal and Empire of Signs co-founder Maxwell August Croy. The umeboshi (梅干, pickled plum) is a staple of the Japanese diet. Among various effects, it's believed to have antibacterial properties, acts as an ageing suppressant and was a common inclusion in a samurai's field ration. Brined in acid, steeped in tradition, rendering life more digestible and not just bitter fruit.
