Prepare for a flood when it comes to live music choices this weekend. Alt-country rockers the Old 97’s shake the Sinclair for a second night on Friday, while Real Estate subtly recalibrates its textural indie-rock at Royale. The same night, Nashville guitarist/singer (and ex-Bostonian music journalist) Ted Drozdowski brings his swampy Americana trio Scissormen to Thunder Road with local blues guitar ace Peter Parcek. And World Music/CRASHarts presents two intriguing shows. Tunisian-born singer Emel Mathlouthi, an Arab Spring activist who mixes electronic rhythms with her melismatic vocals, makes her Boston debut at the Brighton Music Hall on Friday. And on Saturday, Puerto Rican singer/songwriter Draco Rosa, who launched his career with boy band Menudo and co-wrote Ricky Martin’s hits, shares his darker solo fare at the Berklee Performance Center.

Saturday also brings polished hillbilly-country pioneer Dwight Yoakam to House of Blues, while the E Street Band bassist Garry Tallent leads a group that includes Los Straightjackets guitarist Eddie Angel at the Rockwell (formerly the Davis Square Theatre) in Somerville. Saturday’s also a great night for jazz with a Celebrity Series concert at the Sanders Theatre featuring Aziza (pictured), an expansive all-star quartet of bassist Dave Holland, saxophonist Chris Potter, guitarist Lionel Loueke and drummer Eric Harland, while the Regattabar presents classically shaped piano veteran Billy Childs and Scullers Jazz Club offers seasoned sax scion Ravi Coltrane and their respective groups. Pink Talking Fish, a popular jam band that covers Pink Floyd, Talking Heads and Phish, returns to its stomping grounds at the Paradise Rock Club the same night, and the Wailin’ Jennys bring their spirited harmony to the Cabot in Beverly. Fast-rising British soul singer Bishop Briggs brings her trip-hoppy exhortations to the Sinclair on Saturday. Then on Sunday, the same club hosts Pond, an Aussie psych-rock outfit with members from Tame Impala.
