No, it’s not a tribute to Motown crooner Lionel Ritchie. Instead, the musical production “Three Times A Lady” is a cabaret-style show performed at Tango Del Rey on Saturday, Oct. 16. Featuring three singers — Diane Lyons, Jennifer Vargas and Natasha Prantil — alongside musical director Evan Crone, the night mixes stories and light humor with performances of standards, show tunes and pop hits, making this a mini “variety show” of sorts. Three Times A Lady: 7:30 p.m. on Saturday, Oct. 16 at Tango Del Rey, 3567 Del Rey St. $20. 18 and up. www.tangodelrey.com In a club scene crowded with cover bands, eighties tribute band Betamaxx, which appears at RT’s Longboard on Friday, Oct. 22, stands out. The seven-piece group features both male and female lead vocals, but more importantly takes full advantage of their keyboards, giving it less of a programmed feel than some others in their genre. The expanded lineup allows the band to play not only the expected Devo, U2 and Romantics hits, but also the less obvious electronic-based crowd pleasers by Technotronic and Soft Cell. Best of all, the group’s range includes rock and hip-hop — from Springsteen to Salt ’n’ Pepa — making for a fun, if slightly schizophrenic evening of music. Betamaxx: 10 p.m. on Friday, Oct. 22, RT’s Longboard, 1466 Garnet Ave. 21 and up. www.betamaxxband.com The 710 Beach Club will be the site of a benefit for the Alzheimer’s Association of San Diego on Friday, Oct. 22. The night will include music from three groups, encompassing rock from Buzzkills and the Big Decisions and blues from 145th Street. The latter six-piece band specializes in an immensely danceable brand of blues that leans close to funk at times, with MVP status going to sax player Walter Gentry. This is an excellent chance to help a worthy cause while taking in great local music. Alzheimer’s Association benefit: 8 p.m. on Friday, Oct. 22 at the 710 Beach Club, 710 Garnet Ave. 21 and up. $5. www.myspace.com/145thstreet Singer-songwriter Christopher Dale will celebrate the release of his latest album, “Songs I Know The Words To,” with a show at O’Connell’s on Saturday, Oct. 23. One of the area’s best-loved performers, Dale’s latest disc features nine originals combining rock, folk, powerpop and Americana, as well as an inspired cover of the Ramones’ “I Wanna Be Sedated” performed on ukulele. A Dale show is always a fun, anything-can-happen sort of event, but the evening — which will include musical interludes with duo Podunk Nowhere, video screenings and sets in both acoustic and band mode — promises to be special. Christopher Dale: 8 p.m. on Saturday, Oct. 23 at O’Connell’s, 1310 Morena Blvd. 21 and up. Cover TBD. www.myspace.com/christopherdalemusic
