This week, San Antonio music fans have the chance to check out a couple of OG practitioners of their respective subgenres. On Friday, the Meteors, one of the first and most influential psychobilly bands will bring its mix of rockabilly, punk and horror imagery to Vibes Underground, while Dallas-based alt-country trailblazers the Old 97’s will bring its “Holiday Hoopla” show to Gruene Hall that same night. Someone needs to invent a time machine so anybody who’s a fan of both can witness both shows.
