It’ll be a field day for grown-ups. Or at least semi-grown-ups.

The Jackpot Music Hall, 943 Mass., and the Bottleneck, 737 N.H., will host Lawrence Field Day Fest this weekend.

It’s a pretty packed three-day mini-fest sponsored by the Midwest Music Foundation and KJHK and organized by the Dead Girls’ Cameron Hawk.

At least 25 Lawrence bands are billed with promises of “special guests,” especially at the pre-party Thursday at the Jackpot.

All shows are all-ages. Tickets are $10 for the Jackpot show Thursday. Tickets for the shows Friday and Saturday are $10 each day or $15 for a two-day pass. The lineup is below.
