"It's been a long time," frontman Corey Glover told Rolling Stone in a recent interview. "We've been putting this thing together for a number of years now, off and on. Between gigs, soundchecks, going to several studios, cataloging it and deciding what we were going to use. When we got into the studio, we were in a really good place."

The rock quartet, which gained popularity in the late '80s with the hit single "Cult of Personality" from its debut album "Vivid," has won two Grammy Awards--one in 1990 for Best Hard Rock Performance for "Cult of Personality" and another in 1991 for Best Hard Rock Performance for "Time's Up."
