In the basement-level depths of Somerville’s The Rockwell, Minneapolis natives She’s Green stopped by Boston on October 6 for their first U.S. and Canada headline tour for their debut album Swallowtail. The band’s shoegaze sound drew a sold-out crowd spanning generations, underscoring the genre’s cyclical impact since its inception in the late 80s. As fans squeezed into the tight performance space, Brooklyn-based Smush began the night with their unique approach to shoegaze, adding electronic, tinny drum beats and synths over droning guitar. Witches Exist soon followed, featuring strutting drums and frontman Jackson Baker’s one-of-a-kind vocals, which enhanced their raucous sound.

She’s Green took their place on stage and got to work with an expansive guitar sound from guitarists Liam Armstrong and Raines Lucas that reached far beyond the room’s capacity. Bassist Teddy Nordvold entered with a cutting bass line that ran accordingly under Zofia Smith’s floating vocals. Smith’s soft, bright voice joined the guitars in expanding the room as she uttered captivating lyrics. The group made their deep connectivity clear through tight instrumentals and flawless tempo changes.

“Graze” began with Nordvold’s driving bass line and a swaying guitar moment. Smith contributed atmospheric vocals that enhanced the lyrics “Laying on falling leaves / Bury me” and “Swallowed by / The ghosts that haunt me.” Mid-song, the group falls into a raucous breakdown that is led by drummer Kevin Seebeck. Smith also grabs a tambourine and ascends vocally to bring the songs to a soaring end. Afterwards, smiles flashed across the band’s faces before the next song.

Seebeck continued to stand out with intricate, tumbling drumming on “Arrow,” which was also graced with powerful vocals from Smith. For “Mettle,” Smith asked the crowd to jump with her during the energetic chorus. Smith soon felt left out of the fun and hopped offstage to join the jumping audience. As the room bounced, Armstrong and Lucas commenced a shredding duet that pushed the room’s energy further. Despite the crowd’s spanning ages, they danced all the way through the song’s reverberative end.

The group insisted on a group photo with the audience and expressed their gratitude for everyone who came to the show before beginning their last song, “Close Your Eyes.” The song began with cascading guitar that encapsulated the track’s dream motif. The poetic lyrics sung by Smith depict a dream you don’t want to wake up from because you’re spending it with someone you miss. Smith’s lofty vocals embellished the repeated phrase at the end of the song, “I will float, I will fly / When I see you again.” An explosive instrumental served as the base for the intense lyrical longing, bringing the show to a close with guitar that stretched into the stratosphere.
