Waterloo Records is an independent music and video retailer in Austin, Texas, which has been an integral part of Austin's music scene since 1982.
The store takes its name, "Waterloo," from the original name of Austin, briefly adopted in 1839 after being designated as the new capital of the Republic of Texas.
Waterloo regularly hosts in-store performances featuring live performances by local and internationally known artists of all genres, especially during the South by Southwest conferences and festivals during which they host up to 10 bands a day at their festival.
