"Infinity" is the fourth studio album by the American rock band Journey. Released in 1978, it was the band's first album with vocalist Steve Perry and the last to feature drummer Aynsley Dunbar. The album took the band in a new direction toward a more mainstream pop/rock sound, veering away from their previous more progressive rock style. This new sound was developed when band members Neal Schon and Gregg Rolie met Steve Perry. The album is significant in Journey's discography, as it introduced new elements into their music which later became characteristic of their style.
"Infinity" features significant hits from the band, including "Wheel in the Sky" and "Lights", which have remained integral to the band's repertoire. "Wheel in the Sky," "Lights" and "Anytime" all reached the Billboard Top 100 singles chart, helping to catapult Journey into the mainstream of rock music.
The album was met with commercial success, hitting No. 21 on the album charts. Infinity also marked Journey's first RIAA-certified (Recording Industry Association of America) Gold and Platinum album.
The producer of Journey's "Infinity," Roy Thomas Baker, known for his work with other rock giants such as Queen, contributed to the refinement of the band's sound. Together, they created an album filled with catchy hooks, and soaring vocals, a staple sound for the band that would carry on throughout their career. Additionally, Perry's influence and vocal capability added a fresh element to the band's sound, and he quickly became an integral member and defining feature of Journey.
