KARAOKE COMPETITION: The 6th Annual H Street Karaoke Cup — hosted by Little Miss Whiskey’s, Sticky Rice, and Rock and Roll Hotel — kicks off tonight with the first qualifying round at Little Miss Whiskey’s (1104 H Street NE). Anyone may enter, and qualifiers will go on to the final championship battle on February 27th at the Rock and Roll Hotel. 9 p.m. Free.

RECEPTION: The Washington Humane Society’s 2014 Sugar & Champagne Affair at the Ronald Reagan Building and International Trade Center (1300 Pennsylvania Avenue NW) will celebrate “our local crusaders against animal cruelty” and feature the sweet concoctions of local pastry chefs. $150 to attend the VIP Chefs Tasting Room (6-8 p.m.) or $90 for the General Reception (7-9 p.m.). Limited number of tickets available at the door.

MUSIC: Rock out to the Underground System’s “club friendly vibe that blends funk MCing, Italian folk, Afrobeat, and much more” on the Kennedy Center Millennium Stage (2700 F Street NW) tonight. 6 p.m. Free.

OPERA: When you think of singing in a bar, karaoke (see above) is more likely to come to mind than Opera. But tonight at the Black Fox Lounge (1723 Connecticut Avenue NW) local opera singers (Elisa Jablow, Kristina Riegle, Melissa Chavez, Ben Pattison, Brody DelBeccaro) will serenade you over pints. This event, titled “Love is in the Air in honor of the impending Valentine’s Day, is put on by Opera on Tap, “a national non-profit organization that breaks down stereotypes about opera by bringing it to bars, clubs, and other non-traditional spaces.” 7-10 p.m. Free.
