Passion and Warfare is the second studio album by guitarist Steve Vai, released on May 22, 1990, through Relativity and Epic Records.

Passion and Warfare was written based on a series of dream sequences that Vai had when he was younger, and in the guitar music book of the album, Vai sums it up as "Jimi Hendrix meets Jesus Christ at a party that Ben Hur threw for Mel Blanc".

[5] "Blue Powder" was originally recorded in 1986 as a showcase track for Carvin, using their X-100B amplifier, and given away with Guitar Player magazine in flexi disc format.

Like many other releases by Vai, the album is largely instrumental, with only spoken word pieces being featured in terms of vocals, which are performed by many guests.

[7] In 2016, Vai embarked on the Passion and Warfare 25th Anniversary World Tour, where he played the album in its entirety for the first time.
