For an artist who has returned repeatedly to the subject of boundaries and borders in his songwriting, Alejandro Escovedo is blissfully oblivious to both when it comes to his varied musical approaches.  On a night when the weather called for staying in, those who ventured out to the venerable Cat’s Cradle (my first trip) were rewarded with a cross-cultural dynamic that yielded an unleashed hybrid vigor.  Touring in support of his album, The Crossing, with Italian band Don Antônio backing him, the show was a high wattage spectacle from the get-go.
