San Antonio musical artists are repping big this week. Alamo City-based rapper Mike Dimes, whose song “My Story” racked up an astronomical number of TikTok views, is part of a local bill celebrating the iconic Roland 808 drum machine’s contributions to popular music. Meanwhile, Ultra — one of the SA’s hottest rock acts of the ’70s — will help celebrate the 25th anniversary of music mecca Sam’s Burger Joint.
