The A-Town Showdown is the AHS Choral Department's very own show choir competition. The Showdown was started by Alan Alder & Thomas McWilliams in 2007, and was held again in 2008. However, after Alder left in 2008, it was no longer held. Julie Wood revived the competition in 2012, but renamed it Singsational, in honor of the former Highland High School Choral Department's competition. The contest was held up through 2019, but was then cancelled in 2020 due to the Covid19 outbreak.

The A-Town Showdown was revived by Alder and McWilliams in 2024, and is set for February 8, 2025.
