It appears to be a synopsis of this book of his: https://www.amazon.com/End-Biblical-Studies-Hector-Avalos-ebook/dp/B003N642CK/
There is a reasonable auto-generated transcript available on youtube if you're interested enough to scan through one of those, instead of taking a large amount of time to listen/watch.
Edit: I read the transcript. Not a very good talk. He bookends with brief talks about relevance, but the core is about how archaeology has just kept shrinking the possible historical truths of the Bible down. Primary discussion is on the "Gates of Solomon". A couple shitty examples with things like Leviticus' agricultural laws for the relevance thing, some mention of people whitewashing the Bible or skimming over many sections in sermons, and a bit about how little people actually read it. Mostly about the gates, though.
