David Crosby, “Here If You Listen” (BMG)-The veteran countercultural icon may be in his late seventies now but his zest for innovative music-making thankfully remains intact, and his latest collaboration with the gifted Lighthouse Band is an understated joy from the first note to the last. The bulk of the set was penned by Crosby and his cohorts in the space of just a few short days, and the fruits of their labours include gems such as the Little Feat inspired “Janet,” the politically charged “Other Half Rule” and a poignant revival of Joni Mitchell’s anthem for a lost generation, “Woodstock.”
