Tricky date to schedule a concert, Easter Sunday. Lots of people busy with family obligations that day. Meaning that if you hop-hop-hop to it, there's a chance to snatch up a couple of tickets for "The Romantic Piano," the Newburyport Chamber Music Festival concert with Philadelphia-based pianist Natalie Zhu, who is known for intense, emotional performance pyrotechnics. The concert had been all but sold-out on Feb. 5, before mean old Mother Nature put the snow-smackdown on us. So here's to second chances. The concert takes place at 4 p.m. April 24 at The Carriage House, 203 High St., Newburyport — a lovely space with amazing acoustics. The program will include Chopin’s Barcarolle in F-Sharp Major; Rachmaninoff preludes, including “The Bells of Moscow,” and Liszt’s majestic B minor Sonata. Tickets are $30 and can be purchased online.
