Malawians have long been travelers and migrant workers, and as a result, their music has spread across the African continent and blended with other music forms.

By the end of the war, guitar and banjo duos were the most popular type of dance bands. Both instruments were imported. Malawians working in the mines in South Africa and Mozambique also led to fusion and blending in music styles, giving rise to music styles like Kwela. - The Very Best is a collaboration between London-based DJ/production duo Radioclit and Esau Mwamwaya, a singer from Lilongwe, Malawi.

Problem: Information: - Riderch II was , according to the Harleian genealogies , the son of Eugein II , the son of King Dumnagual III of Alt Clut . He is known only from this source , and there is no direct evidence he was king of Alt Clut ( the region around Dumbarton Rock ) , although he is usually regarded as such by scholars . The Harleian genealogies indicate he was the father of Dumnugual IV , evidently his successor as king . - Old Welsh is the label attached to the Welsh language from about 800 AD until the early 12th century when it developed into Middle Welsh. The preceding period, from the time Welsh became distinct from Common Brittonic around 550, has been called "Primitive" or "Archaic Welsh". - The Harleian genealogies are a collection of Old Welsh genealogies preserved in British Library, Harleian MS 3859. Part of the Harleian Collection, the manuscript, which also contains the "Annales Cambriae" (Recension A) and a version of the "Historia Brittonum", has been dated to "c." 1100, although a date of c.1200 is also possible. Since the genealogies begin with the paternal and maternal pedigrees of Owain ap Hywel Dda (d. 988), the material was probably compiled during his reign. The collection also traces the lineages of less prominent rulers of Wales and the "Hen Ogledd" or Old North. Some of the genealogies re-appear in the genealogies of Jesus College MS. 20. - The History of the Britons is a purported history of the indigenous British (Brittonic) people that was written around 828 and survives in numerous recensions that date from after the 11th century. - Dumnagual III (died c. 760) was a king of Strathclyde in the mid-eighth century (probably 754760). According to the Harleian genealogies, he was the son of Teudebur, one of his predecessors. What entity does 'riderch ii of alt clut' has the relation 'date of birth' with?
