這首《巴里東協奏曲》是為贏得2005年BBC電視音樂大賽獎助金(Fame Academy Bursary)的巴里東演奏家卡特莉娜．馬捷拉(Katrina Marzella)所創作的協奏曲。作曲家馬汀．艾勒比(Martin Ellerby)在創作過程中與馬捷拉密切合作，致力將曲子打造成原汁原味的「巴里東協奏曲」，而非「偽裝」成前者的「上低音號協奏曲」。因此作曲家將銅管樂團中的上低音號類比為管弦樂團中的大提琴，巴里東則類比為中提琴，做為構思作品時區別兩者性格的核心概念。
蘇格蘭出身的英國作曲家葛拉姆(Peter Graham, 1958-)是當代首屈一指的銅管樂作曲家之一，為銅管樂團創作的《時間的本質》(The Essence of Time)、《蒙太奇》(Montage)、《地心之旅》(Journey to the Center of the Earth)等原創作品，曾多次被選作各種比賽的指定曲。
