There are multiple artists with this name:
1) Somewhere is a new project from Japanese songwriter Saku https://www.somewhere-official.com
2) Progressive Rock band from Stockholm, Sweden. The nucleus of the band was formed in 2008, but it took until 2010 for the full band to coalesce. Their debut single Bridges was released on August 20th of that year. In December of 2011, they released the first version of their Christmas song The Twelve Days of of Progmas, which to date has had over 50,000 hits on Youtube.
After a series of unfortunate events, including accidents and some turnover of personnel, the band is back in full force as of fall 2013, preparing for their first live event, at Sweden Prog Fest 2013 and the recording of the debut album Magnitizdat
The full lineup is
Fredrik Cerha: guitar/Chapman stick/vocals
Fredrik Lundberg: keyboards
Johan Nyberg: bass/vocals
Mattias Rossipal: guitar/Chapman stick/keyboards/vocals
John E Thelin: vocals/percussion/keyboards
Their tongue-in-cheek slogan is "Death to False Prog".

3) Side projekt of Ghreg On Earth exploring progressive groovy tech rhythms and soundscapes.
