Brian Lesser, the nightlife impresario whose lengthy resume includes the Back Bay club Storyville, is set to open yet another nightspot. Called Tunnel, the subterranean spot below the W Hotel, opens Thursday, and Lesser has big hopes for the space, which he describes as an Ibiza-style dance club melding art, technology, and music. (The club occupies the elongated space that formerly was Descent.) “This is a throwback high-energy nightclub,” says Lesser. “We wanted to create an exciting and exclusive club capable of a wild party, but with an intimate feel.” The club features a sophisticated LED light system — which Lesser considers art in its own right — spanning the ceiling and including thousands of floating LED light fixtures and effects that will be synchronized to music. With two small children at home, and an ownership stake in a host of restaurants and clubs — Minibar, Tavern Road, Sweet Cheeks, Vine Brook Tavern, Bread & Butter, and, soon, Alden & Harlow in Harvard Square — we wondered why Lesser would want to get involved in another venture. “Have you seen the price of college?” he said.
