1. Former Buffalo Philharmonic Orchestra bass player Paul Schmid has played everywhere from Kleinhans Music Hall to the Central Park Grill, delighting listeners with a repertoire that ranges from Dvorak to “My Country ’Tis of Thee.” He comes to the Wednesday lunchtime recital series in historic St. Paul’s Cathedral, 128 Pearl St. at Church Street in downtown Buffalo, for a free half-hour performance at 12:30 p.m.

2. The never-ending rain may put a damper on trick-or-treating tonight, which makes Hallelujah Night, a free family-friendly alternative in Lockport, look all the more attractive. It will be held from 6 to 8 p.m. in Kenan Center Arena, 433 Locust St., for kids up to sixth-graders accompanied by a guardian. It is hosted by community churches and features game booths, giveaways, live entertainment, concession food and lots and lots of candy. For information, call 625-9300.

3. When the doorbell rings this evening at the homes of registered sex offenders, it won’t be trick-or-treaters. The state Department of Corrections and Community Supervision is sending out parole officers to enforce the special Halloween conditions of parole, and they’ve invited preregistered media to ride along. The conditions? Don’t answer the door to trick-or-treaters. Don’t have any candy. And don’t dress in costume.

4. With a theme of “Haute Macabre: From Glam to Ghoul,” the inaugural Witches Ball and masquerade kicks off at 5 p.m. with a zombie walk from Buffalo City Hall to the Hotel @ the Lafayette, where spirited activities continue long into the night. Dark art exhibits will spook the hotel’s hallways, and there will be a steam punk fashion show, fortunetelling and appearances by supernatural historian Mason Winfield and “puppeterror” Franklin LaVoie. Music will be provided by DJ Cutler, the Ifs and Irving Klaws. Tickets are $25 at the door.

5. Buffalo Beer Week takes a frightful turn at this evening’s featured event, Voodoo Doughnut Fright Night, from 8 to 11:30 p.m. in the Pizza Plant in Walker Plaza, 5110 Main St., Amherst. Free samples of Rogue Voodoo Doughnut Maple Bacon Ale and Paula’s Maple Bacon doughnuts will be offered to drinkers in costume. Other Beer Week stops include the Hoppy (Horror) Hour, featuring Southern Tier brews from 2 to 7 p.m. in the Aurora Brew Works, 191 Main St., East Aurora, and Halloween Madness from 5 to 9 p.m. in Fat Bob’s Smokehouse, 41 Virginia Place, with Flying Bison brews.

6. The Screening Room in the Northtown Plaza, 3131 Sheridan Drive, Amherst, climaxes a week of scary oldies this evening with an 8 p.m. showing of perhaps the greatest zombie film of all time, George Romero’s original 1968 “Night of the Living Dead,” which critic Pauline Kael deemed “one of the most gruesomely terrifying movies ever made.”

7. White rappers hold forth for Halloween in the Town Ballroom, 681 Main St. Headliner is Alabama-born Michael Wayne Atha, better known as Yelawolf, self-proclaimed as a “white trash heartthrob.” Opening are up-and-coming Georgia rapper Rittz, whose best-known track is “White Jesus”; Trouble Andrew, who has his own signature brand of sunglasses; and DJ Vara. Doors open at 7. Music starts around 8. Tickets are $25.
