U2 gets away from its roots

I mostly agreed with the review of the U2 concert at the Rose Bowl [“U2 Nurtures ‘Tree,’ ” May 22]. One thing the reviewer missed was that U2’s spiritual side, once prominent, has been diminished. I got into U2 in college because they were unabashedly Christian, singing anthems like “Gloria” and “I Will Follow.” What they’ve done in the intervening years is replaced the righteousness with liberal self-righteousness.
