Family roots, show business and the complications of love are the reoccurring themes on Rachael Sage’s Delancey Street. The veteran indie singer/songwriter draws both upon her Jewish heritage and affinity for folk and cabaret motifs in offering this smart and often bittersweet set. Never a rock belter, Sage maintains a sultry, almost breathless delivery for most of the album, bringing a fresh intimacy to even familiar tunes like Hall & Oates’ “Rich Girl” and the title song from Fame. Her own compositions combine a classy Off-Broadway feel with touches of Brill Building pop and hints of Eastern European balladry. Sage shares some sisterly advice in the frisky “Big Star,” celebrates newfound optimism in “Arrow,” and basks in conflicted nostalgia in the title track. Songs like “Brave Mistake,” “Meet Me In Vegas” and “Back To Earth” show her sophisticated way with romantic material. Sage doesn’t mind getting a little highbrow — “How I Got By” favors words like “ameliorate — but at the core of Delancey Street is a heartfelt quality that goes beyond intellectual exercise. 　　 　　.
