What's on stage now in Boston? For theater aficionados, both "The Motherf**ker with the Hat" and "Ragtime: The Musical" are worthy of note.

"The Motherf**cker with the Hat," which plays at the  Calderwood Pavilion through October 13, is a ferociously funny play about love, fidelity, and facing one’s demons. The story centers on ex-con Jackie, who thinks he has finally turned his life around now that he’s sober and has a new job. But when he finds a strange hat in the apartment he shares with his girlfriend, he is back on the brink, and embarks on a 12-step quest with his AA sponsor Ralph D. to find the hat’s owner.

Based on E.L. Doctorow’s distinguished novel, "Ragtime: The Musical" intertwines the stories of three extraordinary families confronting timeless contradictions of wealth and poverty, freedom and prejudice, hope and despair, and what it means to live in America in the 20th century. The play is running at Dorchester's Strand Theatre until October 7.
