Joshua Marcus plays folk that makes you want to weep. The local acoustic artisan can churn out grievingly beautiful but deviously complex porch-grown Americana both as a burgeoning solo artist and part of a band (after all, he did lead the Fan of Friends helm with emotive polish). It’s a talent he’ll put on display tonight at the M Room, where’ll his old FoF band mates will riff on the axe along with members of Raccoon, National Eye, Dr. Dog, The War on Drugs, American Altitude, Rifle Nice, and the Royalty as Mitch Fiction. Throw in the drunken blues of Brandon Morsberger and headlining New Jersey natives The Roadside Graves, and you’ll be walking the dusty trail as a swelling free spirit – or, rather, it’ll feel that way. M Room, 15 W. Girard Ave., $8, 8pm, 21+ – Annamarya Scaccia
