The Doobie Brothers date back to 1969 when drummer John Hartman arrived in California to join a new line-up of Moby Grape, but instead formed a band with guitarist/singer/songwriter Tom Johnston. Initially called Pud, they evolved into the Doobie Brothers, their powerful, R&B-favoured rock and striking leather-clad image making them favourites with the Hell's Angels. Fuzzy electric guitars, frenetic rhythms and pounding boogie style became the trademark sound which achieved a major breakthrough with their second album Toulouse St in 1972, including the hits Listen To The Music and Jesus Is Just Alright. Adopting a new two-drummer line-up, their third album The Captain and Me produced hit singles Long Time Runnin' and China Grove. As the personnel changed, ex-Steely Dan guitarist Jeff "Skunk" Baxter trail-blazed a new triple guitar front line and, in 1975, the band had their first US Number 1 with Black Water. Singer and keyboard player Michael McDonald became another significant addition to the band as they adopted a more soulful style before splitting in 1982. However, they reunited in 1987 and hit the Top 10 again with The Doctor in 1989 and continue to perform with founder Tom Johnston on lead vocals.
