Loudon Wainwright III with Richard Thompson

Though Thompson’s an English folk-rock progenitor and Wainwright comes from the American singer-songwriter realm, their songs dissecting the human psyche share an affecting poignancy and incisive wit. Thompson, who routinely is found near the top of guitarist rankings, was a standout at the McCabe’s 50th anniversary celebration at UCLA Live in 2008. Wainwright recently lent his wry takes to the “Knocked Up” soundtrack and put new perspective on material from his youth on the album “Recovery.”
