While getting your music into earholes has never been easier, those aforementioned earholes are overwhelmed with options. It didn’t used to be that way. For most of of human existence, people had no instant access to millions of bands or songs at their fingertips. The problem that bands face today isn’t getting their music heard, it’s getting it featured in the supermarket. To help you, the valued music consumer, to shop happily, the National is holding On the Verge: Best of the 804 Locals on Saturday, June 28. The show features up-and-coming groups that play in our regional backyards. On the bill for this month’s showcase are Wake the Captive, Another Treehouse Acquaintance, Lucy in Battle Armor, Relacksachian and Distorted Afterstory. Doors open for this rolling review of unknown local rock at 7 p.m. Admission is $10-$12. thenationalva.com.
