Been listening to a couple early Doobie Brothers albums. Their 1st album, "The Doobie Brothers" and "What Were Once Vices Are Now Habits". Both have good tracks that are never played on radio.
From the 1st album - Nobody & Feelin Down Farther are especially good.
From Vices - Eyes of Silver, Another Park Another Sunday, Tell Me What You Want, Daughters of the Sea stand out.
