The upcoming 20th Annual Ram Jam will celebrate the life of Ramiro "Ram" Ayala, late proprietor of the legendary Taco Land, a wild bar and venue that became a nexus of the San Antonio music underground until his 2005 murder.

The two-day festival, which runs this Saturday and Sunday, will bring together a roster of Taco Land acts, including reunions by no-wave blues outfit Boxcar Satan, pop-punk trio Lucy Loves Schroder, alt-rockers World Bizarre and noise-rockers Chapstik. Other bands on the lineup include Hickoids, Flamin' Hellcats, Michael Martin & The Infidels, Buttercup, Sexto Sol and more.

Music will run 1 p.m. to 10 p.m. both days at the Corn Pound music complex in Windcrest at 6336 Montgomery Drive. The event is free, but donations and sponsorships are accepted.
