Haken bring 'In a Fever Dream' to Ace of Spades with Thank You Scientist and Einar Solberg

The British prog-metal band's first new music since 2023 heads to Sacramento on Thursday, March 11, 2027, on a stacked three-act bill.

For prog fans, the last few years have been a waiting game. Haken went quiet after 2023, then came back this summer with *In a Fever Dream*. Now the music has a Sacramento date: Thursday, March 11, 2027, at Ace of Spades, with Thank You Scientist and Einar Solberg on the bill.

The details first. Haken, Thank You Scientist and Einar Solberg play Ace of Spades in Sacramento on Thursday, March 11, with an early 6:30 p.m. start. The room holds about 1,000. Tickets are through Ticketmaster. The date was announced Oct. 26, and the general on-sale has already happened, so tickets are available now.

The new record is the reason for the trip. Haken returned in 2026 with the single "In a Fever Dream," which Blabbermouth billed as the band's first new music since 2023, and Louder called an epic single. An EP of the same name followed, out digitally on July 17 and on CD and vinyl on Sept. 18. It came with some notable guests: bassists Bryan Beller and Adam "Nolly" Getgood both contribute, with Getgood playing on "Delirium" and "Bleeding Sky," according to No Treble and Blabbermouth.

The tour around it is a two-continent affair. Haken has a UK and Ireland headline run in early February 2027, from Belfast on Feb. 1 to London on Feb. 7, per Prog Report. Then comes the North American leg in March and April, which Blabbermouth announced with Thank You Scientist and Leprous frontman Einar Solberg as support. The schedule also includes a Cruise to the Edge stretch in early April without Solberg, so Sacramento gets the full three-act version of the bill.

That support lineup is a draw on its own. Einar Solberg is the voice of Leprous, one of the more distinctive singers in modern prog, here as a solo act. Thank You Scientist bring their own brand of horn-laced, technically wild prog. Put the three together and you have a night that rewards people who listen closely — the kind of show where the crowd counts along to time signatures.

Ace of Spades makes sense for it. At roughly 1,000 capacity, it's the size where a band like Haken can bring a full production but still feel close, and where intricate parts don't turn to mush in a cavernous room. For Sacramento prog fans who might otherwise drive to the Bay for a bill like this, having it on a weeknight downtown is a win.

Practical notes: with three acts and a 6:30 p.m. start, the night begins early, so plan to arrive on time if you want to see Solberg's set. Tickets are on sale through Ticketmaster.

Three years between new music is a long time in any genre. On March 11, Sacramento gets to hear what Haken did with it — loud, precise and right in front of you.
