E.P. Thompson, especially Making of the English Working Class (One of my favorite books ever, by the way.)

Eric Hobsbawm

Raymond Williams

I've never read Hobsbawm myself, but I know he's a big deal. Williams is more of a cultural historian/literary critic, but from a historical materialist perspective that may dovetail with your interests.

All three are British, by the way.

The book Dust Bowl: The Southern Plains in the 1930s by Donald Worster adapts something of a neo-Marxist approach towards environmental history. He interprets the Dist Bowl not so much as an environmental catastrophe, but one of the consequences of an unbridled capitalist exploitation of the land.

Although many conservative ideologues call Eric Foner a Marxist, he's pretty canny about writing history without overtly ideological frameworks, such as his survey The Story of American Freedom, in which it is clear which side of the ideological fence he sits on, but less so why.

Ruling America: A History of Wealth and Power in a Democracy, an anthology edited by Steve Fraser and Gary Gerstle scrutinizes the role of elites in American life, but inverts the "great man" paradigm and instead the entries in the anthology generally argue elite power has suborned the promises of American democracy.

Good marxist or otherwise left-wing historians currently working, I would put Eric Foner (social) and Bryan Palmer (labour, social, cultural) on a short-list.

In the past, as noted, EP Thompson's work is amazingly erudite and forceful. In general, the British marxist historians were a solid lot. Christopher Hill (chronicler of Milton, Bunyan, and Cromwell) is the main reason I pursued history at the graduate level. Perry Anderson's work is often very interesting.

Hobsbawm, your mileage will vary because he left behind such a massive canon. If you don't mind reading a tough-minded critique written by an unmarxist Noel Malcolm (a massively brilliant historian in his own right), you can get a sense of Hobsbawm at his weakest: A fondness for opinions rather than evidence.

These may be of interest to you.

American Insurgents: American Patriots by T.H. Breen examines the Committees of Safety and the role they had in expanding democracy.

The Unknown American Revolution: The Unruly Birth of Democracy and the Struggle to Create America by Gary Nash focuses on crowd action in the Revolutionary Period.

The First American Revolution: Before Lexington and Concord is well worth reading. Ray Raphael has done quite a bit of work in this area.

Revolutionary Founders: Rebels, Radicals, and Reformers in the Making of the Nation edited by Ray Raphael, Gary Nash and Alfred Young might be of interest.

The Revolution Is Now Begun: The Radical Committees of Philadelphia, 1765-1776 by Richard Alan Ryerson examines the role of the radical committees of Philadelphia on the American Revolution.

Rebels Rising: Cities and the American Revolution by Benjamin L. Carp isn't necessarily Marxist, but it does focus on the mass protests by the people, rather than focusing on a top down history, so it might be of interest to you.

The Minutemen and Their World by Robert Gross is another book that, while not necessarily Marxist, does take a look at the common people. It's a history of Concord in the Revolutionary era.

Bury My Heart At Wounded Knee by Dee Brown covers the same territory as Zinn's A People's History but is more rigorous.

Changes in the Land: Indians, Colonists, and the Ecology of New England by William Cronon is an environmental history of New England and the impact of colonization on it.

Cadillac Desert: The American West and Its Disappearing Water by Marc Reisner examines water usage in the American West, particularly the craze/fascination with building dams.

In responding to another Reddit thread, I came across this conversation about Marxist historians on the U.S.:

http://s-usih.org/2012/10/a-list-of-marxist-historians.html - it pertains specifically to the United States.

I strongly recommend Wallerstein, who draws on Ferdinand Braudel's historical work in Modern World Systems, which is a multivolume history of modern capitalism.

I recommend Robert Brenner, his Merchants and Revolution and Economics of Global Turbulence are great. The Brenner Debate is also an excellent edited volume containing an important scholarly debate on the origins of capitalism. I also recommend Ellen Meiksins Wood.
