The Bitter End seems to be the club in New York to find classic-rock style bands. Tonight Red Moon was a gritty-sounding New York-based power trio performing original songs influenced by many contemporary sounds. Bronx-born vocalist/bassist Scott Fanzo offered gutsy, bluesy vocals over his funky bass progressions. Guitarist Rene Ferrer intoned the hard rock riffs and jazz-rock leads into the mix. Drummer Sergio Leccese kept the rock and roll beat. The trio tonight invited Cara Delevingne to sing a sultry cover version of Prince's "Kiss." Red Moon brought back the innovative rock spirit that dominated the same venue some 40 years ago.
