When boy-band hitmakers LFO (for Lyte Funkie Ones) get onstage nowadays, they have more than a few good-timey hit songs to deal with. “It takes my breath away, to be honest with you,” says Brad Fischetti, the sole survivor of the original trio. And we get people crying, but in the end they’re happy tears.”Breaking out of New Bedford in the mid ’90s, LFO (Fischetti, Rich Cronin and Brian Gillis, replaced by Devin Lima) marked a new generation of rap/R&B-inspired boy bands; to them the New Kids on the Block were old school. ‘Summer Girls’ changed our trajectory in that way; we weren’t a boy band in the same way the Backstreet Boys or ‘NSync were. A friendship developed and O-Town singer Trevor Penick is now filling some of the gap in LFO.
