The band 's history can be roughly divided into three eras. From 1970 to 1975 it featured lead vocalist Tom Johnston and a mainstream rock and roll sound with elements of folk, country and R&B. Johnston quit the group in 1975, and was replaced by Michael McDonald, whose interest in soul music changed the band 's sound until it broke up in 1982. The Doobie Brothers reformed in 1987 with Johnston back in the fold and are still active, with occasional contributions from McDonald. Every incarnation of the group emphasized vocal harmonies. The Doobie Brothers were inducted into the Vocal Group Hall of Fame in 2004.
