Jeff Miller The we’re-never-going-to-play-together-again-to-lucrative-reunion trail is well-worn at this point — just ask such famously feuding acts as the Eagles, Guns ‘N Roses, Pixies and, most recently and famously, Oasis: If there’s a windfall, there’s a way. But maybe the least-likely ‘90s-era reunion of the year isn’t actually that of the Gallagher brothers, which seemed eventually inevitable: it’s Soul Coughing, the proudly weird cult-favorite NYC-based jazz-meets-poetry-meets-alt-rock foursome whose drugs-and-disparagement 1999 breakup was discussed in excruciating detail in singer Mike Doughty’s autobiography, “The Book Of Drugs,” leading fans to believe it would be impossible for the band members to talk again, let alone play music together.
