In Autumn of 2004, Archive announced that Dave Pen (BirdPen) would replace Walker on the "Noise" tour. During this same tour, Keeler and Griffiths met the singer Pollard Berrier (formally of the band Bauchklang) at one of their shows in Vienna, Austria. Pollard had given Darius a demo CD of his own written material, with the intention of starting another project with Dan and Darius. Because of the latter circumstances, the three began writing and rehearsing together, and were recording in Southside Studios, London, by September 2005. A new modern era for Archive had begun with Darius, Dan and Pollard all writing and co-writing seven tracks and Dave Pen co-writing three, on the album, "Lights". Maria Q sang on three (including backing) tracks. From this point on, Archive was no longer a "front-man-band", but a "collective" of individual artists contributing to what is now an established sound. The album "Lights" was released in May 2006 and received high critical acclaim in France, Switzerland, Greece and Poland. Archive enjoyed predominantly sold-out gigs on their "Lights" Tour, as well as high acclaim at festivals around Europe.
