The Alumni Band had its humble beginnings in 1994 where a number of old boys and girls came together and set up the a band specifically for alumni. Its purpose was to meet the needs of the growing number of alumni members of the Bands of the ACS family of schools. The number of members then were relatively small for a wind band, thus the name The Anglo-Chinese Wind Ensemble (ACWE).

The Wind Ensemble was tasked with two main goals. First and foremost, it is to give graduated members a chance to continue their love and enjoyment for music through performing. In addition, it serves to develop a strong sense of cohesion among the Old Boys and Girls of the band by providing the opportunity for them to meet up regularly.

It was through the undaunting ACSian spirit and the enthusiasm of these pioneer members that saw an inaugural concert held at the Victoria Concert Hall on 1st April 94. This successful concert led a number of other concerts spanning the next few years till today.

The governing authority of the Alumni Band lies with a committee formed from the members, overseeing the planning and operations of the non-profit organisation, often with advise from The ACS OBA.

As membership increased, the name - Anglo-Chinese Wind Ensemble, no longer portrayed the proper role the Alumni Band, and thus a concensus was reached to have the name changed to Anglo-Chinese Wind Orchestra. This brought about the start of changes and improvements in the way the alumni band operated.

A reorganisation was in order, which saw more involvement of the younger generation. This is especially true for the graduating batch of 1997. This year, in line with the ACS family of schools, the Anglo-Chinese Wind Orchestra will henceforth be known as the ACS Wind Orchestra.

In the forthcoming years, the ACSWO seeks to establish ties with all who have made the ACS bands the premier bands in Singapore today, and provide a niche for those who wish to continue with this love and interest.
