First king in Rwanda's history

Twenty was an arena concert by Filipino entertainer Regine Velasquez. It was announced in September 2006 and held on two consecutive nights in October 2006 at the Araneta Coliseum in Quezon City. Its concept and name is a reference to the 20th anniversary since her professional debut in 1986. The staging resembled a Roman colosseum connected by a grand staircase extending from the upper box gallery. The setlist predominantly contained songs taken from Velasquez's discography and various covers. The show was produced by Aria Productions, with GMA Network as its broadcast partner. Ronnie Henares served as stage director and Raul Mitra as musical director. Guest conductors were featured, including Louie Ocampo and Gerard Salonga, backed by the 60-member ensemble of the Manila Philharmonic Orchestra. It received positive reviews from music critics, who praised Velasquez's vocals and the production.

Kigeli IV Rwabugiri was the king (mwami) of the Kingdom of Rwanda in the mid-nineteenth century. He was among the last Nyiginya kings in a ruling dynasty that had traced its lineage back to Gihanga, who is one of the first 'historical' kings of Rwanda whose exploits are celebrated in oral chronicles. He was a Tutsi with the birth name Sezisoni Rwabugiri. He was the first king in Rwanda's history to come into contact with Europeans. He established an army equipped with guns he obtained from Germans and prohibited most foreigners, especially Arabs, from entering his kingdom.
