In-A-Gadda-Da-Vida is the second studio album by the American rock band Iron Butterfly, released in 1968. It is most known for the title track, a simple composition which, due to an extended jam, occupies the whole of Side B. The album is also available in a deluxe edition CD.

Vincebus Eruptum (the first word is pronounced 'win-kay-bus') is the debut studio album by American rock band Blue Cheer. Released in January 1968, the album was the first to feature the band's classic lineup of vocalist and bassist Dickie Peterson, guitarist Leigh Stephens and drummer Paul Whaley. A commercial and critical success, Vincebus Eruptum peaked at number 11 on the Billboard 200 albums chart and spawned the top-20 hit cover of Eddie Cochran's "Summertime Blues". It is lauded as one of the first heavy metal albums.
