The Doobie Brothers & Michael McDonald at iTHINK Amphitheatre

For the last five decades, The Doobie Brothers have a mainstay of rock and roll, with a bevy of radio hits, including "Listen to the Music," "Black Water," "China Grove," "What a Fool Believes" and "Long Train Runnin'," and nine gold and platinum albums in the US. When the band began in 1970, the had a traditional rock sound, with some folk, country and R&B influences, and they were fronted by lead singer Tom Johnston. When Johnston left the band five years later, Michael McDonald stepped in, who brought with him a taste of blue-eyed soul. The group disbanded in 1982, and when they reunited five years later, Johnston, once again, took the lead. Ever since, they have toured and recorded together as a band, with McDonald stepping in to join them every so often as well. The Doobies Brothers were inducted into the Vocal Group Hall of Fame in 2004, and they were nominees for induction into Rock and Roll Hall of Fame in 2020.
