The weekly Monday night blues series continues Oct. 10 with a double show at the downtown Time Out Pub, 275 Main St. The Columbus Day event starts an hour earlier, at 6 p.m., and features performances by the 24th Street Wailers; and Jason Ricci and the Bad Kind. Admission is $20 at the door.

The 24th Street Wailers promise All Killer, No Filler! and their non-stop touring across the United State, Canada and Europe have tested and proven the formula. The band’s five musicians originally met in music school; as the 24th Street Wailers, their major influence are the freewheeling period in the 1940s and ‘50s, when the blues gave birth to rock ‘n’ and roll.

The band is led by Lindsay Beaver, a “wild and crazy” front woman who sits in back because she’s also the drummer. The 24th Street Wailers is filled out by Michael Archer on upright bass, Marc Doucet on guitar, Jesse Whiteley on piano and Jonny Wong on wailing sax. They have been winning over the masses with high-energy live performances and a sense of showmanship from a time gone by.

Maine native Ricci is listed in almost every Top 10 list of harmonica players online. Through two-plus decades of endless touring, TV appearances, recordings and the internet, Ricci has put out a style of playing so influential there exists an entire younger generation of players imitating his music, clothes, gear and even stage presence.

Nicknamed “Moon Cat” (a street name he once used in Nashville and New Orleans to avoid police detection), Ricci has been an almost constant, sometimes polarizing, force for decades through performing, singing, songwriting, teaching and activism for LGBT, mental health and addiction. The white, queer, skateboarding, punk rock-loving convicted felon won a 2010 Blue Music Award for Best Harmonica Player, as well as receiving multiple BMA nominations from 2009 forward. Ricci was a featured performer on Johnny Winter’s 2014 Grammy Award-winning CD “Step Back” and, last year, at the Rock & Roll Hall of Fame with Zac Brown and Tom Morello for the Paul Butterfield Blues Band induction.

Next up in the weekly series is another double show: on Oct. 17, both the Anthony Gomes and Joanna Connor bands will perform. Admission is $15 and the music starts at 6 p.m. Gomes also is playing the night before, 6 p.m. Sunday, Oct. 16 ($15). Rounding out the month are: Oct. 24, Regina Bonelli Band ($10); and, Oct. 31, a Halloween Party with Harper ($15).
