The group recently announced that they are reforming after 11 years to play Coachella festival, and have since announced that they will also perform at Benicassim.
Rodriguez-Lopez told Kerrang!: "Will there be a new album? No, no, no. At The Drive-In is more of a nostalgia thing – it's songs we wrote when we were all in our 20s and we're doing a couple of shows.
"It's an old T-shirt that doesn't fit me any more, but when you put it on again, it feels nice. It's as simple as that."
Rodriguez-Lopez also expressed his surprise that the reunion had come as a shock to some, adding that band members had patched up any disagreements some time ago.
"For the rest of the world, [the reunion] seemed to be out of nowhere, but we've been hanging out for the past four years," he added.
Rodriguez-Lopez also told NME that being reunited could be "weird", joking: "It's like getting back with your ex-wife, only in this case there are four ex-wives!"
At The Drive-In posted an image featuring a map of Europe on their official Twitter page prior to the Benicassim announcement, possibly hinting at further live shows.
