A sign on the door of the Body Actualized Center in Bushwick, Brooklyn, promised “Cosmic Yoga,” but on a recent snowy Monday night, a crowd had gathered for a concert of electronic music. Slushy boots were politely confiscated in the lobby, and about 75 shoeless patrons in their 20s and 30s sat cross-legged on pillows or reclined on blankets on the floor. The space was lit, just barely, by botanica candles, placed amid potted trees and colorful crystals. The aroma of incense permeated the room.

In front of the crowd, Mark McGuire, the former guitarist of Emeralds, stood behind two synthesizers, summoning a pleasant drone. While some concertgoers closed their eyes and rocked gently to the thrumming, Mr. McGuire added a crackly recording of a lecture on “The Universe According to Esoteric Philosophy” by the mystic Manly P. Hall. Eventually, Mr. McGuire began to loop a phrase of Hall’s — “The only reason for existence is this perpetual growth”— until the words were distorted beyond recognition. Then he began to play guitar over it, first fluid and crystalline, then fiery and molten. The sound waves buffeted the dream catcher that hung from the ceiling just enough to make it twirl slowly.

Mr. McGuire, 27, a Cleveland native who lives in Los Angeles, began his career in the Midwestern hardcore punk and noise scenes. Today, he’s one of several musicians whose music reflects a confluence of psychedelia, electronic music and those genres’ eccentric cousin, new age. A generation of younger musicians with an affinity for analog electronics have re-examined this long-derided category with open minds, borrowing liberally from new age’s sonic palette: hypnotic repetition, gauzy textures, spacey guitar noodling and soft, bright synths.

Elements of new age can be found among a diverse range of artists, including Julianna Barwick, Sun Araw, Bitchin Bajas, Matthewdavid and Greyghost. “New-age music now has the contemporary electronic underground and the noise underground infused in it, as well as the spirit of all the different musics that have evolved since then, so I think it is something new,” Mr. McGuire said. “The gear has evolved, but the consciousness behind it has, too.”
