As we creep slowly through the last breath of summer, we’re all looking for an excuse to play hooky from work. Here’s a really good one: 1970s R&B singer and multi-instrumentalist Shuggie Otis brings his soulful groove to a free show at the Metrotech Commons (the corner of Flatbush and Myrtle avenues) in Downtown Brooklyn this Thursday, Aug. 8. The catch? It’s smack dab in the middle of the work day. Touring in support of his recently re-released cult classic Inspiration Information, Otis is a masterful musician who started gigging with his father, R&B legend Johnny Otis, before he was old enough to get into the music clubs he played at. This event, which starts at noon, is the last in BAM’s free summer R&B Festival at Metrotech, and with Otis on stage, the series isn’t going out quietly. So go ahead and take a long lunch or use one of those sick days you’ve saved up and settle in for some silky smooth afternoon delight.
