When the House of Blues opened on Lansdowne Street in 2009, much was made of the chain venue’s roots in Harvard Square. Three years later, live music on a grand scale is returning to the Cambridge neighborhood.
Bowery Cambridge, an extension of the New York concert booking agency that operates Royale under Bowery Boston, will announce as early as next month THE SINCLAIR, a planned 10,000-square-foot multi-level live music venue and eatery at 50 Church Street, the site of the former firehouse-themed restaurant and nightclub Phatt Boys, which shuttered in 2006.
