Could Cave headline Merriweather?
i doubt it. i don't think he has enough pull to fill the pavilion let alone sell any lawn tickets. he sold well at strathmore, but that's easier to get to and holds less than 2,000. moving a venue ten times bigger and harder to get to seems like an iffy proposal. mind you, i have no idea what the break-even point is for MMP. maybe selling 3,000 or 4,000 tickets is enough to make a show viable.
maybe if he co-headlined with someone that also has decent pull.
