ERASURE

Longtime British electropop duo Erasure has a new album, “The Violet Flame,” and it sounds true to their ’80s heyday but with clear affection for contemporary dance music. Vince Clarke and Andy Bell have done club-friendly remixes of their music in the past, and the songs on the album reflect that dance floor consciousness while maintaining the spare, percolating sound that defined them.

GENERATIONALS

New Orleans’ Generationals alternate album styles — a sleek, spare indie rock disc followed by one of poppier, more technological ear candy. On their fourth, “Alix,” Ted Joyner and Grant Widmer are in a glossier phase, where they show their affection for ’ 80s new wave textures.

The sound’s not retro, though, and the songs are strong enough that they don’t rely on a flicker of nostalgia or a full flush of trendiness to catch.

DRU HILL AND SWV

The “Fall Jam Fest,” as the show is titled, brings ’90s R&B back with the reunited Dru Hill and SWV.

The former has three original members including Sisqo, who had a solo hit with “Thong Song” in 2000, and both have been featured in reality TV shows. In 2010, Dru Hill’s reunion was a part of “Keith Sweat’s Platinum House” on the Centric channel, while SWV has been the subject of the WeTV reality show, “SWV Reunited.”

Both will perform for real, with the real Mannie Fresh also on the bill.
