Magna Carta is a British progressive folk-rock band formed in 1969 by Chris Simpson, Lyell Tranter, and Glen Stuart. Known for their intricate acoustic guitar work, harmonies, and poetic lyrics, they gained popularity in the 1970s with albums like Seasons and Lord of the Ages. Over the years, the lineup changed frequently, with Chris Simpson remaining the core member. Magna Carta developed a loyal fan base, particularly in the UK and the Netherlands, and continued performing and recording into the 21st century.
