Brainbox is a Dutch rock group that was initially active from
1968 until 1972, and then reformed in 2009. Brainbox is best described as a progressive blues rock band infused with jazz elements. Their eponymous debut album, released in
1969, is also the only Brainbox record that features founding guitarist Jan Akkerman, who left the band in late 1969 to join Focus. Nevertheless, Brainbox is considered a legendary Dutch band of international allure. Brainbox is now available as a limited edition of only 500 individually numbered copies on purple vinyl.
