So Solid Crew are an English garage, grime and hip hop group originating from Battersea, London which achieved wide success in the early 2000s. The group consisted of a large number of members, the most notable being Lisa Maffia, Romeo and Harvey. They are generally credited with having paved the way for the current generation of crossover UK hip hop stars. 　　Before breaking into the mainstream market, So Solid Crew were involved with many pirate radio stations in London, such as Supreme FM and Delight FM. It was at Delight where they made their name, occupying most of the Sunday schedule, the so-called "So Solid Sundays". From around lunchtime until 10 pm, there were shows from different members, where the various So Solid Crew DJs would play 2-step garage tracks. At times, the So Solid Crew emcees would rap on top of tracks for up to two hours each session. On Christmas Day in 2001, So Solid Crew performed their last Sunday show on the station. 　　Trigger is now working with UK/US based producer Clyde Ward on his solo project JAX and features in UK-based band The Fallen's debut album track, "Maybe". 　　In February 2013, the group announced its 2013 tour.
