House of Soca Tent in Bridgetown
Barbados's longest-running calypso tent, tracing back roughly to 1980 and staged at a vocational school auditorium in Bridgetown. It has a distinctive history of platforming disabled performers, including a multiple-time Blind Calypso Monarch, alongside a junior development programme training new talent for future seasons of Crop Over calypso.
House of Soca is old enough that a 2015 anniversary report already put it at 35 years running, which places its founding around 1980 and makes it, by most local accounts, Barbados's longest-standing calypso tent.
