Originally released on the ATCO label in 1969 and 1970. 'Ball' was the follow-up album to 'In-A-Gadda-Da-Vida' which spent a staggering 140 weeks on the US Album chart. 'Ball' didn't disappoint, reaching No.3 and staying in the charts for nearly a year, also spawning the hit 'Soul Experience'. 'Metamorphosis' made the Top 20, again providing a hit, 'Easy Rider'. Iron Butterfly is still in existence today but with a much-changed line-up. Digitally remastered and slipcased. New notes.
