April 8. Mother Fletcher is Hudson’s biggest local draw, and amusingly calls its music “Ameri-ska-na”: a quirky, high-hopping, danceable brew that, yes, takes ska as its jumping-off point, and adds rock, hip-hop, reggae, and gypsy folk. The band’s self-titled debut utilizes the standard guitar/bass/drums set-up but also sports fiddle, conga, horns, and harmonium, and was recorded at Catskill’s Old Soul Studios under the expert ears of Kenny Siegal (Johnny Society). Past performances have seen the group paired with local drag diva Musty Chiffon—perhaps she’ll grace us with a surprise appearance at this Club Helsinki date? Never rule anything out when it comes to these guys. (Spottiswoode and His Enemies return April 8; Club D’Elf with John Medeski groove in April 9.) 9pm. $12. Hudson.
