There are several bands named Mayday. Mayday is also well known as a recording moniker of Derrick May.

One is a metallic hardcore band from Virginia Beach, Virginia in the 1990s. They released two 7"s, a 10" and a split with Integrity. While they were never particularly popular, they were fairly influential as one of the first hardcore bands to incorporate very overt metal elements.

The other is an indie rock band from Nebraska.

Like the teenage death ballads of the '50's, Mayday casts an odd sort of instrumentation and lyricism into romantic ballads of the afterlife. Percussive, choral, upbeat, morbid, scatological, rootsy-indie-wit. A bluesy kuntry mythological storybook. Bushido Karaoke travels from the Old West ("Song of the Scaffold") to the modern one ("Hidden Leaves"), from Australia to Mesopotamia ("Old World New World"), to hell and back ("Standing in Line at the Gates of Hell") and into the caverns of history.

Featuring the talents of Mayday’s usual suspects: Ted Stevens (Cursive, Lullaby For The Working Class), Tiffany Kowalski (Lullaby For The Working Class, Head of Femur), Dan McCarthy, and Pat Oakes; plus a list of able conspirators that is too sprawling to fit on a one sheet. Full U.S. tour planned for summer '05.
