What is "tubthumper"

Tubthumper is the eighth studio album by the British band Chumbawamba, and is the album that catapulted them into the mainstream, released by EMI in the UK and in the US by Universal Records. Many of the tracks address specific social issues, such as homelessness, the Liverpool Dockers' Strike or racism; a fair number of them express the far-left/anarchist critiques of British liberals in " New Labour," which started in 1994. Tubthumper was the band's first major commercial success, and remains their most successful album, selling over 3 million units in the United States alone, largely on the strength of the hit lead single " Tubthumping". Cover design for the album's U.S. release was designed by Michael Calleia at Industrial Strength Design in New York City.
