The pressures of touring and internal friction culminated in 2006 when Justin Hawkins checked into rehabilitation for alcohol and cocaine abuse. Shortly after, he announced his departure from the band, leading to an indefinite hiatus. During this period, the remaining members formed the band Stone Gods, while Justin formed Hot Leg. Reunion and Continued Career

The music of The Darkness is characterized by twin-guitar harmonies, driving riffs, and Justin Hawkins' signature use of falsetto. Lyrically, the band balances genuine emotion with a heavy dose of British wit, self-deprecation, and camp humor. Songs often tackle classic rock tropes—love, sex, and rock and roll—alongside absurd or mundane topics, such as the local physical education department in "Growing on Me."

The success of Permission to Land was consolidated at the 2004 Brit Awards, where the band won Best British Group, Best British Rock Act, and Best British Album. They quickly became one of the most prominent live acts in the world, known for Justin's habit of riding through the crowd on the shoulders of a security guard or a giant suspended platform while playing guitar.
