21,000 people, many of them teen and tween girls and their parents, out for a good time at a concert. For at least 22 of them, it was the last night of their lives. The tragic suicide bombing that took place outside an Ariana Grande show in Manchester, UK hit home to a number of musicians, many of whom are still smarting from the Paris massacre at le Bataclan during an Eagles of Death Metal show. As details continue to emerge, many artists are weighing in on the tragedy.
