Subsignal is a progressive rock band. The band was originally formed as a side project by Sieges Even members Arno Menses (vocals) and Markus Steffen (guitars). After their main band disbanded, Menses and Steffen recruited former Dreamscape members Ralf Schwager (bass), David Bertok (keyboards) and Sun Caged drummer Roel van Helden to complete the line-up.
