Nah it’s the guys themselves, they’re posting all the SBDs for the North American tour as they go by the looks and they’ve also said they’ll be eventually putting up the stem tracks so people can make their own mixes if they want. Pretty incredible stuff but it’s totally something you’d expect king gizz to do at this point.

It’s all about how much silica is in the lava - not much and you have basalt, fairly runny so the gas escapes and you get fire fountaining and lava flows. More silica gives you very viscous lava like rhyolite or andesite - traps the gases, far more explosive and dangerous eruption styles.
