Ball is the third studio album by the rock band Iron Butterfly, released in February 1969. After the enormous success of "In-A-Gadda-Da-Vida", Iron Butterfly modified its acid-rock sound somewhat and experimented with more melodic compositions. The band's trademark heavy guitars, however, are still evident on such tracks as "In the Time of Our Lives" and "It Must Be Love". The album reached #3 in the charts, making Ball more immediately successful than In-A-Gadda-Da-Vida. Ball was certified Gold in March 1969. It also spawned two minor hit singles: "Soul Experience", an uncharacteristically uplifting song for the group, went to #75 on the Billboard charts, and despite its nightmarish musical tones and morbid lyrics, "In the Time of Our Lives" managed to reach #96.
In 1999, Collector's Choice Music released Ball with two bonus tracks, "I Can't Help But Deceive You Little Girl" and "To Be Alone", which previously were available only on a 7" single.
Allmusic's Stephen Thomas Erlewine rated Ball three out of five stars. He explained that the quality "is wildly inconsistent", but that it "was a more ambitious album" than In-A-Gadda-Da-Vida. He concluded by calling it "a more consistent album than their two previous records".
