Writing about Northern Soul as a genre defies some of the easy shorthand that a part time music critic and admitted hack like myself might otherwise reach for. And by that I mean that, despite its name, it is a musical movement defined not by how and where the music was created and played — as opposed to, for instance, “Philly Soul”, or “Delta Blues” — but by how and where it was consumed and curated. In my case, learning that it was, in fact, a British musical movement based around overlooked American soul records — and hence an antecedent to contemporary DJ and “crate digger” culture — was one of those “a-ha” moments that sees something perceived only dimly from the periphery of experience suddenly come sharply into focus. Aiding that focus was Charly Records’ just released double disc Up All Night!: 56 Northern Soul Classics, which not only provides an expansive musical overview of the scene, but also stands as a testament to its enduring appeal. The set combines two seminal Northern Soul compilations first released by Charly on vinyl in the early 90s and again on disc a few years later. In the reissue process, the label this time around also saw fit to include a brief but informative set of liner notes from veteran music journalist Bob Fisher and a generous helping of bonus tracks that include some of the best tunes on the comp overall.
