Repress! Trials & Errors is a live album by Magnolia Electric Co., released on Secretly Canadian in 2005.

It was recorded on April 16, 2003, at Club Ancienne Belgique in Brussels. It was the first Magnolia Electric Co.

album released under that name, even though at the time of recording the band still toured under the Songs: Ohia moniker.

The album itself is made up of ten original songs, all but three of which were at the time unreleased, but contains three fragments of Neil Young songs, including the show-closing chorus of "Tonight's the Night" at the end of the song "The Big Beast", as well as the Young tunes "Out on the Weekend" and "Walk On".
