Rock legends are set to electrify the Alamodome come August, and they’re bringing a tidal wave of hits to San Antonio. In what was announced as a “major concert announcement” by KSAT, Def Leppard and Journey are teaming up for a sprawling 23-city North American tour this year, with Live Nation pulling the strings on what promises to be another cash cow. The Alamodome officials delivered the news at a 10 a.m. press conference that was promised to rock the city’s music scene.
