“Big Jazz Jam at the Albemarle” part of the Albemarle Concert Series.

Where to Jam in and around Hull -
Hull Jazz meets at the Goodfellowship on Cottingham Road and there are a few Players' Nights in the programme where you can jam with the house band. Admission is £3.00
There is a monthly Jazz Jam at the Polar Bear; the band is a bit more funky and the audience is younger. Admission is free but please make a donation to pay the house band!
If there are a small group of you there are quite a few pubs and cafes that have open Mic nights or afternoons (but no house band) - such as the St Johns, Alexandra Hotel, Communull, Nostalgia - check local listings or social media to find them, or ask around.
Lewis Kilvington runs a monthly Guitar jazz jam in North Ferriby.
Matt Smith organizes a saxophone collective
