Andrew is currently Divisional Music & Gospel Arts Director for The Salvation Army in the Wisconsin & Upper Michigan Division, USA. In addition to this role, he holds the positions of Editor of SA Bandsman magazine, Composer in Residence to Virtuosi GUS Band and Artistic Advisor to Illinois Brass Band. He was previously a graphic designer for Salvationist Publishing & Supplies and World of Brass.

Andrew was born in Hastings but spent his early years in Africa, where he became interested in music through his membership of The Salvation Army. After completing two years of a BA Graphic Design degree, he embarked on a BA Music Degree at Middlesex University, which he completed in 2005.

Andrew first received acclaim for his compositional skills when in 1997 he came runner-up in Performance, The Arts Channel's Young Composer of the Year for Great Britain. However, his biggest compositional project to date was arranging Karl Jenkins' hour-long work, The Armed Man - A Mass for Peace for brass band, choir and organ. It has been performed by numerous groups across the world and a CD was produced of the work in May 2007, followed by a DVD by Black Dyke Band in 2010 of a live performance at Birmingham Symphony Hall. More recently, Andrew's arrangement of Karl Jenkins' Stabat Mater was premièred by Cory Band at the European Brass Band Championships in Montreux, Switzerland and has since been performed by the band at Symphony Hall, Birmingham and broadcast on BBC Radio 2. In early 2013, he was also commissioned by Black Dyke Band to arrange Jenkins' Gloria.

Andrew has been commissioned to write solos for Brett Baker, David Daws, David Childs, Chris Jeans, James Fountain, Les Neish, Michael Baker and Sheona White, as well as several arrangements for ITV's 'Britain's Got Talent' star Faryl Smith and former BBC Radio 2 Choirgirl of the Year, Lucy Rhodes. He has had a number of pieces published by various companies and has had compositions played by Black Dyke, Cory, Foden's, Fairey's, The International Staff Band, Virtuosi GUS Band and the Brass Band Aid Celebrity Band.

As a performer and tutor, Andrew has completed tours to the USA, Switzerland, Portugal, Cyprus, Norway, Denmark, Kenya and Zambia. He has played with a number of musical groups including Brass Band Aid Celebrity Band, Clarence Adoo Brass Band and Hendon Band although the highlight of his playing career was performing with World and European Champions, Cory Band, at the Royal Albert Hall in October 2008. Andrew was for seven years a member of Kettering Citadel Band and featured regularly as a baritone soloist on concert programmes, including on the band's latest CD,That's the Spirit, where he performs Variations on the Carnival of Venice on baritone. He is currently a member of the Chicago Staff Band.

Andrew has been responsible for the organisation of a number of charity concerts, in particular the acclaimed 'Brass for Africa - A Musical Spectacular' series which raised close to £12,000 for various African projects.

In 2010, after a spell of just over two years with Virtuosi GUS Band on baritone and contributing a number of compositions and arrangements to the band's repertoire, he was delighted to be appointed as its Composer and Arranger in Residence.

In March 2012, Andrew was privileged to be a guest of the New York Staff Band for its 125th Anniversary weekend and was commissioned to write a piece for the occasion, 'Fanfare & Theme on Before the Throne'. Andrew conducted the combined bands of the New York Staff and 'Future All Stars' in his piece in a special concert.

In November 2012, a CD of Andrew's music was released by Virtuosi GUS Band, featuring Faryl Smith. Entitled 'Christmas Fantasia - The Music of Andrew Wainwright', it was launched on the Doyen label.

Away from music, Andrew is a keen football fan and his claim to fame was designing Arsenal Football Club's mascot, Gunnersaurus Rex, which makes an appearance at every home match!
