The Band

31EVEN DAYS is made up of the leader and guitarist, Brock Cook, Bass Player, Lenny Leonard, and Drummer, Mutt. The band formed in 2025 when Brock was playing in another band and wanted to focus on a larger project. While he remains in his previous band, he focuses the majority of his time on 31EVEN DAYS. He has also joined Mutt’s long running band, Pictures of Lenny, on guitar. While Mutt is the drummer, for the demos, he has stepped in on vocals while they are searching for a permanent vocalist.

The Name

The band is always getting asked about their name. The name originated from a musical Brock was in. He had a line where he said, “11 days!” He thought it would be an amazing band name. However, the name was already taken by some band in another country. That’s when Mutt suggested 31Even Days, because the 31 looks like “El” making 31even look like Eleven. While the name is now pronounced 31 Even Days, the band uses the number 11 in a lot of material.
