Say what you will about live albums: The applause distracts from the music! People scream too much! But really good ones give you insight into the performer’s personality and, if you’re lucky, a bit of spur-of-the-moment humor. During the course of two recorded shows at the Atlas Performing Arts Center this weekend, local singer-songwriter Laura Tsaggaris hopes to make a great one. She’ll draw inspiration from some of her favorite live albums (e.g. Nirvana’s MTV Unplugged in New York and Fleetwood Mac’s The Dance) and play a set featuring tracks from her three released albums, as well as one new song that she’ll debut onsite. While most of her songs fall under the larger umbrella of rock, her 2013 album, Everyman, tilts more toward roots music, with pedal-steel accompaniment by Marty Rifkin and Ryan Adams on backing vocals. Unlike Adams, who gained attention for kicking a fan out of a live show in 2002, expect a milder interaction between listeners and the decidedly likeable Tsaggaris. Laura Tsagarris performs at 8 p.m. Friday and Saturday at Atlas Performing Arts Center, 1333 H St. NE. $35. (202) 399-7993. atlasarts.org.
