Incubus' seventh studio album 'If Not Now, When?' has been in stores for just under a month now and the band is gearing up for the supporting U.S. tour. The California alt-rock quintet dropped by Jimmy Kimmel Live! to warm-up with new tracks 'Adolescents' and 'Promises, Promises'.

Incubus are about to embark on a 31 date tour of the U.S. with opener Tom Morello (as The Nightwatchman) that kicks off on August 17th at Denver, Colorado's Red Rocks Amphitheatre. The band has just announced that they will stream that concert in it's entirety via LiveStream.

While 'If Not Now, When?' has received mixed reviews due to it's lack of intensity, the album is still sitting at #51 on the Billboard charts.

Their performance of 'Promises, Promises' on Kimmel was kind of a snoozefest. The performance itself was fine, but the song plays like elevator music for hipsters. Even the crowd seemed uninterested (except for the Brandon Boyd groupies which make up half of Incubus' audience at any given show) as 90% of them stood motionless recording the band with their cell phones.

Incubus picked things up a bit with their previous single 'Adolescents' (neither have made a big splash at radio), you can watch both performances below.
