If you’re looking for a demonstration of how musical instruments can be put through their paces with spot-on technical skill, check out Alex Lofoco and his band. Yes, his lengthy multi-part compositions are as demanding as they are dazzling. Yes, they might bewilder the casual listener due to their periodic chaos and transitions that are more abrupt than gradual. But we believe that “Resurrection,” “Earthquake” and “The Spear” will reward listeners who have an ear for progressive music by players at the top of their game. Lofoco’s bass work, the way he attacks his axe, is a thrill to behold, and suggests he and his band would do well to engage a booking agent who can put them in front of a prog-hungry audience.
