It's been revealed that SID will release a new single (currently untitled) in November.

SID is scheduled to hold a series of "gender-specific" concerts this summer starting on August 1 at TSUTAYA O-EAST. It will be about a year since the band last released a single.

More details will be announced at a later date, so stay tuned!
