The Duke Spirit's latest album, Neptune, came out almost a year ago, so their performance on Jimmy Kimmel last night was as much in promotion of the band as it was an individual album. After an intro from Kimmel pimping the limited edition of their debut album, Cuts Across the Land, the band proceed to knock out a raucous version of Neptune's "Lassoo" with lead singer Leila Moss dominating the performance.
