Happy Birthday, Houston ย— you donย’t look a day over 150! Not that anyoneย’s counting candles (itย’s 172, for those who are). The weekendย’s celebrations start with the River Oaks Chamber Orchestraย’s intimate salon recital featuring Rodney Waters on the piano and the orchestraย’s founder and Executive Director Alecia Lawyer on the oboe. Just one of many events planned for the cityย’s birthday (August 30, 1836), todayย’s concert will be followed on Saturday by a family day at the Downtown Aquarium, a tour of Olivewood Cemetery (the cityย’s first incorporated African-American cemetery) and a tour of St. Arnoldย’s Brewing Company (nothing historic here, just lots of beer). On Sunday, thereย’s a wreath–laying ceremony honoring Houstonย’s founding mothers. Snag the complete celebration schedule from the Save Our Historic Landmarks Houston Web site. Meanwhile, hear the beautiful River Oaks Chamber Orchestra today from 5:30 to 7:30 p.m. The Alliance Franรงaise de Houston, 427 Lovett Boulevard.
