Answer
In Utero, released in 1993, marked a departure from Nirvana's polished sound on their previous album, Nevermind. It showcased a raw, abrasive style with distorted guitars and introspective lyrics, reflecting the band's personal struggles and disillusionment with the music industry. The album's themes of isolation, addiction, and self-destruction resonated with fans, solidifying Nirvana's status as one of the most influential grunge bands of the era.
