Regi Dias - Dias Brazil Quartet Reginaldo Dias was born in Urai a small village in the Brazilian countryside. He first played percussion in the local marching band before moving on to trumpet in his early youth. His first music teacher was the fittingly named, Saul Trumpet. Reginaldo's military service was spent with the Brazilian army band after which he studied trumpet for 4 years at the Federal University of Paraiba on the way to his Bachelor's degree in Music. Reginaldo has worked in many musical styles including Brazilian folk, classical, jazz and pop. Since founding Dias Quartet and Dias Brazil in 2005, Reginaldo has developed his compositional skills as well as his vocal and dancing talents. As well as trumpet, in Dias Reginaldo also plays traditional Brazilian instruments such as the cavaquinho, pandeiro, berimbau, cuica and conch shell.

Terry Sloan - Dias Brazil Quartet Drummer Terry Sloan described in the Edinburgh Evening News as 'a direct, unfussy performer' with 'nimble fills and in-the-pocket timing' has recorded and performed within many settings ranging from musicals, jazz orchestras and big bands through to pop, rock and new wave groups. Terry was first introduced to Brazilian frevos and sambas in 1994 by renowned Canadian ceilidh drummer Jim Walker, and further developed his interest in Brazilian and Latin music in Jafala, the Edinburgh-based international jazz-funk-latin sextet featuring ex-New Yorker Jess Abrams and Swedish saxophonist Diana Leverington. He also played in the Edinburgh and Napier University Jazz Orchestras under the tutelage of trumpeter Eddie Severn through whom he was fortunate to study with both Sebastian De Krom and Greg Hutchinson. In 2002, in the Edinburgh Music Theatre production of 'Return to the Forbidden Planet', Terry played drums in 'the eight-piece big band, led by Peter Horsfall, which if it was any tighter would snap' - The Scotsman 28/02/2002. Terry has been with Dias since its inception in 2005. Originally from Glasgow, Terry now lives and works in East Lothian, Scotland. Terry studied jazz at the University of St. Andrews with Richard Ingham and Richard Michael and holds a Graduate Diploma in Jazz with special endorsements in Performance and Keyboard. His dissertation was on the Afro-Cuban origins of the modern jazz ride cymbal pattern.

Iain Carleton - Dias Brazil Quartet Iain Carleton was born in Ayr and was encouraged to learn to play the guitar by his father who showed him a few chords and tunes. He went on to study classical guitar with Harry Broad and then jazz guitar with Ienne Hunter and Neil Munro. Iain has played in many bands mainly on guitar, sometimes on bass guitar, in several styles including rock, pop, jazz, folk and latin. He has studied music (Certificate in Music Studies) at Edinburgh University with Bill Alexander, St. Andrews University (Advanced Diploma in Jazz Performance) with Richard Ingham and holds an LLCM (TD) from the London College of Music. Iain has for many years worked as a freelance tutor, performer, composer and transcriber.

Stuart - Dias Brazil Quartet Stuart grew up listening to an electic mix of musical styles. His father was a member of a local samba band. He would often be woken by the sound of the surdo vibrating through the walls of the family home. This experience created in him a love of Brazilian music and the rich low end of the double bass. Although new to the Edinburgh music scene, Stuart is already performing in various projects around the city, playing a wide mix of styles.
