In late September 2005 Sonic Boom, alias Pete Kember – historical founder member of Spacemen 3, Spectrum and Experimental Audio Research – meets Julie’s Haircut at Studio Alpha in Bologna to cooperate with them to the final editing of their new album (“After Dark, My Sweet” - 2006). This was a new starting point for Julie’s Haircut in the field of music research… only a part of 3 days of studio recordings was released in that album. N-Waves / U-Waves contains, for the first time, two takes released in that session.
