Comedian Greg Giraldo, a native New Yorker and Harvard grad, is releasing his long-anticipated debut album, Good Day to Cross a River. Weaving raunchy social satire into fluid performances, Giraldo tackles everything from the onset of middle age (i.e. sagging testicles dipping into toilet water) to unemployment and illegal-immigrant weathermen (hence the album title). A taping from his strong-language standup routine, Giraldo’s album sticks to semi-current events like prosecuting older women for having sex with young boys and how far mothers have to go these days to be “the cool mom,” then moves on to a new reality show idea called “The Floater,” in which paraplegics are tossed into a pool to see which one floats. Giraldo has provided unrelenting commentary on Colin Quinn’s former series “Touch Crowd” and taken part in a score of Comedy Central roasts, lighting fires under infamous characters like Pamela Anderson and William Shatner.

Christian Finnegan, another slowly rising comedy star, offers a brilliant mix of intelligent observations and crude imagery that bridges the gap between fat guys in wet T-shirts and “Strunk and White” references. The self-proclaimed Biff look-alike (from “Back to the Future”) also has a knack for pulling off successful audience interactions, and the album — taped from a live performance — perfectly showcases these improvisational skills.

Finnegan is an unashamed nerd who revels in his geekdom. In one act, when he calls out to his fellow nerds in the audience to little response, he then denounces them as cowards and accuses one unsuspecting member who didn’t raise his hand of running the projector in grade school. Often, the grammar school jokes go over his audience’s head, but he’s happy to poke fun at himself and anyone else who understood the reference — all the while using energetic, and often vulgar, charisma to keep the rest of the crowd rolling in their seats.
