Dappy and Fazer, who had already started rapping together, decided they wanted a female voice in the group, which was called the Lickle Rinsers Crew at the time, and so invited Tulisa to be part of the group. They started performing together as a group around Camden from young ages. For N-Dubz's second album, Tulisa did a solo song called "Comfortable". Performing as the Lickle Rinsers Crew, they released the singles "Bad Man Riddim" and "Life Is Getting Sicker by the Day", which became hits on pirate radio stations. After Lickle Rinsers Crew, they then became NW1, after the area they hail from, making their first music video in 2005 for the track "Everyday Of My Life", which received airplay on Channel U, recording more demos as NW1 such as "Don't Feel Like Moving", "Girl On Road" and "Livin Broke". Their first single to be released was "You Better Not Waste My Time", which was available for download only until their 2006 self-released single, "I Swear", which gained them their first mainstream notice. It wasn't until 2007's "Feva Las Vegas" (also self-released) that the group appeared on the UK charts, peaking at No. 57.
