1. Beer & Ice Cream Pairing at Lazarus Brewing

6 to 8 p.m. April 16. $40. 1902 E. Sixth St. eventbrite.com/e/beer-ice-cream-pairing-with-lick-honest-ice-creams-and-lazarus-brewing-tickets-59180430260.

Indulge in two of our biggest vices with this beer and ice cream pairing between Lazarus and Lick Honest Ice Creams. The two local brands kick off a series of these pairings with one that gives back to charity. All of Lick's proceeds will be given to the Hill Country Ride for AIDS. A ticket will get you five 5-ounce beer samples with five 1-ounce ice cream scoops of assorted Lick spring flavors. Plus, reps from both Lazarus and Lick will be there to educate you on each option.

2. KUTX The Breaks Live at Empire

8 p.m. April 16. $3-$5. 606 E. Seventh St. empireatx.com.

Confucius and Fresh from the KUTX Saturday night hip-hop show, the Breaks, continue their monthly concert and interview series at Empire. This installment features the Williams family, whose Carnival Beats production company created beats to iconic Texas rap tracks like Mike Jones’ “Still Tippin’,” Paul Wall’s “Sittin’ Sideways” and Big Moe’s “Purple Stuff.” Soul dynamo Tomar Williams is listed as a featured performer, but we expect brother Salih Williams (the mastermind behind Carnival Beats) will also bring the noise, and second-generation Williams performers might, too. — Deborah Sengupta Stith

3. Astronomy on Tap

7:30 p.m. April 16. Free. The North Door, 502 Brushy St. astronomyontap.org.

The next installment of this popular series exploring the mysteries of the universe comes about a week after the very first image of a black hole was published to the world, so no doubt that's going to be a topic of conversation. In fact, one of the topics this month is about how active black holes affect the evolution of galaxies. Astronomy on Tap also will have telescopes so you can look for exciting objects in the night sky, weather permitting.

4. Fusebox Eve

7 to 10 p.m. April 16. $200-$250 tickets. 1300 E. Fifth St. fuseboxfestival.com/fusebox-eve.

Fusebox Festival kicks off with a fundraiser the night before that helps to keep the fest completely free. At its heart, the evening is a dinner featuring food from some of Austin's top chefs, who took their inspiration from different mountain ranges across the world, such as Mount Vesuvius that L'Oca D'Oro chef Fiore Tedesco will represent. Plus, there will be performances by the Octopus Project, Dana Suleymanova and cellist Jeffrey Zeigler of the Kronos Quartet.
