If Not Now, When? is the comeback album by Incubus after a half decade hiatus. Just like their success albums A Crow Left of The Murder… and Light Grenades, Brendan O’Brien covered the production for the band.
The producer, who is best known for producing records for Pearl Jam, Korn and Audioslave, helped reinventing their sound.

The band’s seventh installment is recognized by less use of guitars compared to their earlier works. 
The album reached #2 in the US Billboard Charts. Singles “Adolescents” and “Promises, Promises” ended up in the Billboard Alternative and Rock Charts.
