The 12-piece blues-rock outfit headlines Berkeley's open-air Greek Theatre on a Wednesday night, with Lukas Nelson as support. Doors 5pm, show 6pm.

Tedeschi Trucks Band headlines the Greek Theatre this Wednesday, August 12, with Lukas Nelson opening. Per the Greek Theatre's official calendar: doors 5 p.m., show 6 p.m., at the William Randolph Hearst Greek Theatre, 2001 Gayley Road, Berkeley — up the hill on the UC Berkeley campus.

A mid-week bill this size is the news here. TTB is a 12-piece led by guitarist Derek Trucks and singer-guitarist Susan Tedeschi, built for exactly this kind of room — a warm night, an open sky, long jams that stretch past the setlist. And the support is no throwaway: Lukas Nelson (Willie's son) fronts a country-rock outfit that headlines its own theaters. Get there for his set, not after it.

Tickets are through AXS, per the venue. Price and whether it's sold out weren't confirmable as of Sunday — check axs.com or the Greek's box office before you count on walking up.

The access detail that matters: the Greek has almost no parking of its own, and the campus lots up Gayley Road fill fast on show nights. Take BART to Downtown Berkeley and walk the ~20 minutes uphill, or budget real time to circle for street parking in the residential blocks below campus. It's a general-admission-heavy venue; the earlier you're through the gate, the better your spot on the terrace.

If you've only got the evening: get in by 6 for Lukas Nelson, grab a spot on the lower terrace before it packs, and let TTB's second set — where the long jams live — be the reason you stay to the end.
