This EP featured several guests, two of them being bassist/vocalist, Kristian Wikstøl, lending both his bass and vocal skills to this release and drummer Anders Haave.
In late 2005 the band were then joined by bassist Ole Vistnes and guitarist Magnus Olav Tveiten, and began to write and record their first full-length album.
Close to 20 guest musicians participated in the recordings, amongst them Jan K. Transeth, Kjetil Nordhus and future bassist/vocalist Kristian Wikstøl on hardcore vocals.
Just before the band began playing live gigs they were joined by bassist/vocalist Kristian Wikstøl who replaced former bassist Ole Vistnes.
The bassist, Kristian, decided to study abroad for two years, taking a break from In Vain, but with the intention to return afterwards.
[clarification needed] The drummer, Stig, was working in Korea and his replacement was Baard Kolstad from Borknagar, ICS Vortex, Ihsahn and Solefald.
The guitarist Kjetil were shortly unavailable due to family commitments, and his replacement were Petter Hallaråker from ICS Vortex and Rendezvous Point.
In an announcement on Facebook, In Vain have said "The album title, Currents, reflects on the colossal shifts and changes of our time.
These enduring shifts are some of the topics that In Vain addresses on Currents through a series of epic and monumental songs."
