Carabao (Thai: คาราบาว) is a Thai rock band that is very popular in Thailand and other Asian countries. The group was formed in 1981 by university students Yuenyong Opakul (Aed) and Kirati Promsaka Na Sakon Nakhon (Keo or Khiao) who met while studying at Mapúa Institute of Technology in the Philippines. The word carabao means "buffalo", a symbol of fighting, hard work, and patience. They are known for their Phleng phuea chiwit (เพลงเพื่อชีวิต) or 'songs for life'. This kind of music came to prominence through the protest songs of the 1970s political upheaval in Thailand, especially from the band Caravan. Carabao have blended the acoustic/folk style of 'peua chiwit' with other forms of Thai music, western rock and country music, and various kinds of world music like Latin music and reggae, earning such labels as 'ethnic rockers' and 'Kings of 3Cha' or 'Rolling Stones of Asia'. MTV Asia calls them "veteran". Carabao's songs often tackle social and political issues, demanding social justice and taking on the causes of the ordinary Thai people, but they have also created love songs and more philosophical songs that carry messages for people everywhere. Lead singer/songwriter Aed Carabao is loved by many and is also famous for his sharp tongue and open criticism of corrupt politicians, big business, and environmental destruction. At least one or two songs on most albums up to the mid-'90s were banned by the government and coverage of the band rarely appeared on government TV and radio stations. Despite this, Carabao is the most popular Thai rock group of all time. Carabao reached cult status long ago and is now one of the most successful legendary rock groups in the world. They have been compared to the rock band U2.
