Originally formed in 1981 as St. David's High School Brass Band, it  was comprised of school pupils from St. David's High School under the baton of John A Dickson.  The band's first contesting appearance came in 1986 at the Scottish Youth Championships winning at the first attempt.  Following this, in 1991 the band broke new ground and entered the Scottish Championships Fourth Section for the first time. 

As years went by many of the pupils from the school decided that they would like to continue playing after they had finished their schooling years and so in 1997 the band adopted a formal constitution with the name St. David's Brass Band and registered as a Scottish Charity.  In 1998 the band won its first senior event by winning the Scottish 4th Section Title playing 'Solemn Melody' (Henry Davies) and 'Scenes from a Comedy' (Michael Hopkinson).  Later in 1998 the band was also awarded Lottery funding that allowed the purchase of a full set of instruments to replace the original ones some of which were older than the Grandparents of those playing them. 

The band has played at many high profile events throughout the years including representing Scotland at the British Brass Band Championships on 3 occasions, playing for the Princess Royal in Holyrood Park, playing National anthems at Scotland's 6 Nations Rugby matches at Murrayfield, broadcast on BBC Radio Scotland and also on Dutch Radio when in Germany. Players have also triumphed in solo and quartet contests and have held the East of Scotland titles on many occasions. 

Over the years the band has had many contesting successes including in 2004 when winning the Scottish 3rd Section and also being the Scottish 3rd Section Band of the Year in 2010-2011, a year which saw the band claim many scalps of bands ranked in the sections above throughout.  Players have come from as far afield as Norway, Peterhead, Glasgow, Edinburgh and the Lothians and even, on occasion, Australia to play in the band with players ranging from university lecturers to primary school pupils.
