Iron Butterfly's second album, In-A-Gadda-Da-Vida, was cut from the same cloth as contemporary outings by fellow LA luminaries The Seeds, The Music Machine and The Strawberry Alarm Clock, yet it outshone them all. In-A-Gadda-Da-Vida sold in excess of one million copies in its first year alone and became the soundtrack to the summer of 1968, its 17-minute title track defining a generation of stoned alternative rock fans. In-A-Gadda-Da-Vida has taken on a life of its own, having been used in many films (Manhunter, Resident Evil: Extinction) and TV shows (The A Team, Seinfeld, The Simpsons - twice!), as well as being covered (Slayer, Boney M) and sampled (Beck, Nas) numerous times.
