VISUAL VACANCIES: Last week, the Dallas Museum of Art announced that director Bonnie Pittman will be leaving her post in May due to health reasons. Not only does that leave two of the Arts District’s institutions without leadership (the AT&T Performing Arts Center is still without a CEO), but it also means that two of the state’s top museums have vacancies at the top. The Museum of Fine Arts, Houston has yet to replace Peter Marzio, who ran the museum for 28 years before his death in December. The Texas Tribune (via nytimes.com) writes that replacing a civic legend is a tricky process.

LIQUID SOUND: On Friday, the Fort Worth Symphony Orchestra will perform Tan Dun’s Water Concerto. And making sound out of that water will be percussionist David Cossin, who tells dfw.com that the inconsistency of the medium’s sound is one of the things he enjoys most. “With this piece, I spend most of my time trying to develop my technique so I can get certain sounds from the water, but it’s not foolproof. But that’s the beauty of it, too. If you do something a little different, you can expand on that and it sounds like a new idea,” he says.

TRIPLE DIGITS: Congratulations to the folks over at Art This Week, who just posted their 100th video. This time, they speak with Scottish artist Jim Lambie about his brightly colored installations at the Goss-Michael Foundation.
