Welcome back, Sonny. . In 1962, it had been three years since Sonny Rollins had released a record. Frustrated with what he felt was his own limitations, he took sabbatical to work on his form, practicing at the Williamsburg Bridge. This odd habit led to his comeback album being named "The Bridge". A quartet record featuring guitarist Jim Hall, bassist Bob Cranshaw, and drummer Ben Riley, invariably this album and it's story is the stuff of legends, and deservedly so. Rollins is on fire throughout-- playing mostly standards (with only two originals), it sounds as if he was itching to get in the studio again, his playing is powerful, focused ("Without a Song"), lyrical (one of the definitive readings of "God Bless the Child") and emotive ("Where Are You?"). Rollins' support is generous and sympathetic, particularly on "God Bless the Child", where Cranshaw in particular feels like he's breathing in time with Rollins. All in all, a worthwhile effort, and an essential point in Rollins' catalog. It also may be the best place (either this or "Saxophone Collosus") to begin exploring Rollins' catalog. Highly recommended
Output:
POS
