Willie Nelson

7:30 p.m. Tuesday, August 22. UMB Bank Pavilion (14141 Riverport Drive, Maryland Heights).

Willie Nelson, music's most prolific country outlaw, long ago said "pshaw" to the Nashville dream machine. Instead, he chose to forge a legacy of tangled-but-truthful hits — "Crazy," "On the Road Again" and "Always on My Mind," to name a few — that he delivered with a reedy, Whiskey-River-soaked twang in his tenor and a twinkle in his eye. All-American yet wholly original, the Red Headed Stranger also stands as an inspiration to environmentalists, pot smokers and income-tax evaders everywhere — and even today, at 70-plus years young, he continues to roast country music's sacred cows, as on his recent gay-caballero cover, "Cowboys are Frequently, Secretly (Fond of Each Other)."
