Before Chester Bennington was singing for Linkin Park, he was fronting a band called Grey Daze. The band put out two albums between 1994 and 1997, and was working on a new one before Bennington's death in 2017. Grey Daze ultimately put out a record called Amends featuring Bennington's vocal takes, but apparently that's not all they had from the vocalist.
Grey Daze has announced they're working on another new record, an unspecified amount of which will feature Bennington. The band has also revealed they're working with Dave Navarro (Jane's Addiction) and Richard Patrick (Filter) on the new album. Stay tuned as we learn more!
