Ponytailed, German-born pianist Markus Groh has a reputation for tackling big classical works. And they don’t get much bigger or much more classical than Beethoven’s Eroica Symphony, which Groh is performing with the Houston Symphony this weekend. Its multiple emotional hues and impressive length (more than twice as long as the average symphony of the era) kicked off the Romantic Period, according to some classical experts. And if Groh doesn’t add enough international star power, the symphony is also bringing in Finnish conductor Hannu Lintu to lead the performance. 8 p.m. Thursday and Saturday, 2:30 p.m. Sunday. Jones Hall, 615 Louisiana. For information, call 713-224-7575 or visit www.houstonsymphony.org. $25 to $116.
