PORT CHESTER, N.Y. — Phil Lesh has logged countless miles on the road as the bassist of the Grateful Dead and, since the late 1990s, in various post-Dead ensembles. But at 73, he is looking for a change.

“I’m done with one-nighters,” he said before a Phil Lesh and Friends show on Friday at the Capitol Theater here. “I’ve been on the road now for 46 years, and I’ve gotten go to a point where I’m jealous of all the time that I waste on buses and sitting around waiting to go on.”

Grayed and wiry, and still visibly in love with music, Mr. Lesh said he had been searching for a way to play regular concerts yet avoid the grinding tedium of the road. He has found it with an unusual deal to work exclusively with one promoter for 2014, putting on 45 shows in just a handful of venues.

The plan — an indie-scale version of the megadeals that stars like Jay Z and Madonna have made with Live Nation Entertainment — will pair Mr. Lesh with Peter Shapiro, a big Grateful Dead fan who owns the Capitol and runs the Brooklyn Bowl, the combination bowling alley-rock club in Williamsburg that is setting up branches next year in Las Vegas and London.
