The husband-and-wife team of Amanda Sudano and Abner Ramirez, aka Johnnyswim, is touring in support of its first full-length CD. “Diamonds” (Big Picnic Records) is multifaceted and beautifully polished. If many of the songs inevitably find their way into romantic you-and-me-against-the-world thicket, they have more than enough charisma and talent to blaze an engaging trail. Both members of the singing and songwriting team have strong voices. Sudano, daughter of late disco diva Donna Summer, adds a soulful touch that complements Ramirez’s more country-tinged approach. The record has a big sound, guitars, violins and multi-tracked vocals. But judging by online live videos with just the two singing with acoustic rhythm guitar, less may be just as much. They play at 7:30 p.m. on Thursday, May 15, at Camp Concert Hall in the University of Richmond’s Booker Hall of Music. Tickets are $10-$20. For information visit modlin.richmond.edu.
