As Alternative Press recently reported, the music community is mourning the loss of veteran executive Craig Aaronson. Aaronson is most-known for his involvement in signing acts like My Chemical Romance, the Used, Taking Back Sunday, Mastodon and more. He lost a long battle with cancer yesterday (Oct. 29).

The iconic exec handled A&R (artists and repertoire) at Warner Bros. Records, and before that worked for Capitol; he first signed Jimmy Eat World in 1995 for their album ‘Static Prevails’ and then worked 1999's 'Clarity.'

After his time at Warner Bros., he most recently found himself working with Hundred Handed -- the label that released Coheed and Cambria’s ‘The Aftermath: Descension.’

As you can imagine, musicians and fans took to social media to share their condolences:
