Loso Loso (Thai: โลโซ) is a Thai rock band fronted by singer-guitarist-composer Seksan Sukpimay (aka Sek Loso). The band was formed in the mid-1990s in Bangkok, Thailand. Its name is derived from a play on hi-so, Thai slang for socialites and the upper class, and is meant to reflect the group's humble origins. It is one of the first Thai bands to achieve success on the international music scene, having played festivals, including South By Southwest and Glastonbury, and to be produced by a Western record producer.
