She has toured with acts including Suki Waterhouse, Horsegirl, and Porridge Radio and has performed at South by Southwest, Austin City Limits Music Festival, and on The Tonight Show Starring Jimmy Fallon.

[11] Her father exposed her to classic rock[5][6][7] and took her to her first concerts: The Rolling Stones's 2005 performance at Madison Square Garden on their A Bigger Bang Tour, and a Cher show in Las Vegas.

[3][6] Seeing Jersey Boys on Broadway was also a formative musical experience for her, as were Adele's 19 and Amy Winehouse's Back to Black albums, which she learned to play on piano.

[26] She was scheduled to perform in April at Boston's Middle East nightclub with singer Dagny but cancelled due to a case of bronchitis.

[25] Teitelbaum was inactive for much of the year that followed, in part due to personal turmoil including her mother's death, a breakup with her boyfriend, and a split with her manager.

[3][34] A second Blondshell single, "Kiss City", was released the next month,[35] reaching over 900,000 Spotify streams and garnering praise from Rolling Stone and The New York Times.

[43] In October, she appeared at the 2022 Austin City Limits Music Festival alongside Teezo Touchdown, Omar Apollo, and Wet Leg.

[46][42] The Waterhouse tour included stops at the El Rey and Fonda theatres in Los Angeles and at South by Southwest;[7][13][41] at the latter, Blondshell performed at Spin's Five Worlds party, sponsored by Diageo, alongside Urban Heat and Chulita Vinyl Club.

[6] This sound, which Teitelbaum initially labelled "natural grunge",[18] was compared to artists like Haim,[18][26][22][25] Carly Rae Jepsen,[22][58] Muna,[18][58][26] Lana Del Rey, Adele,[61] Lady Gaga, Lorde,[12] and Tei Shi.

[26] Debut single "First" was infused with elements of jazz,[17] while "Fuckboy" was described as "Halsey-ish",[7] with a music video visually evoking Haim, Maggie Rogers, and the drama series Euphoria.

[14] This style has drawn comparisons to '90s alternative artists like Liz Phair, PJ Harvey, Fiona Apple, Hole, Belly, Throwing Muses, Veruca Salt, and The Cranberries,[68][13][7][69] as well as modern singer-songwriters like Phoebe Bridgers, Soccer Mommy, Snail Mail, Olivia Rodrigo, Japanese Breakfast, Boygenius, and Courtney Barnett.

[7][36][9][70][71][47][72][73] Technique compared the non-album single "Cartoon Earthquake" to "if Katy Kirby sang a slower, melancholy-tinged version of “I Won’t Back Down” by Tom Petty.

"[71] Matt Mitchell of Paste Magazine wrote of her debut album, "No two songs sound alike, yet Blondshell is not a collage of subgenres.

Instead, it’s Blondshell tinkering with her own renditions of sonic palettes previously mastered by the artists she got really stoked on during the pandemic, like Hole, Nirvana and Patti Smith.

[75] As a child, Teitelbaum's father introduced her to classic rock artists including The Beatles, The Rolling Stones (she became "obsessed" with Tattoo You after seeing them live),[3] Bob Dylan, David Bowie, Eric Clapton, Neil Young, Cher, and Janis Joplin.

[5][3][6][7][12] Other early influences included mainstream pop artists like Avril Lavigne, Ashlee Simpson,[46] Adele, Amy Winehouse, Madonna (one of her early songs "accidentally plagiarized" Madonna's "Hung Up"),[4] and Teenage Dream-era Katy Perry;[57] local NYC legends like Patti Smith and The Velvet Underground;[6] and singer-songwriters like Tracy Chapman, Elliott Smith, Feist, and PJ Harvey.

[5] During her BAUM iteration, Teitelbaum cited influences including Frank Ocean, Bon Iver, SZA, The 1975, Tierra Whack, The Japanese House, The Twigs, and Sharon Van Etten.

[57][5][13][6][42] Across her career, Teitelbaum has praised the music of Nilüfer Yanya, Jamila Woods, Dominic Fike, Sasami, Gus Dapperton, Caroline Polachek, Joji, Daniel Caesar, Julia Michaels, Dionne Warwick, Cardi B, and Ethel Cain.

[24][25][5][3] At the time of the first Blondshell album's release, she had been listening to Big Thief's Dragon New Warm Mountain I Believe in You and the music of Indigo De Souza.

[77][49][11] She had obsessive–compulsive disorder as a child that was treated with cognitive behavioral therapy,[11] and she began taking Adderall in high school to help her study for exams and deal with weight gain.
