Baby Bushka at the Casbah February 15

Tribute bands tend to pay homage to long-gone acts, rather than still-extant groups who might compete for ticket sales, but British singer-songwriter Kate Bush performs so rarely that few are likely to have caught her in concert. More’s the pity, since Bush’s operatic brand of theatrical prog-pop is so well suited for stage presentations, something that’s not news to the members of local all-star Kate Bush tribute Baby Bushka.

Steve Poltz 15th Annual 50th Birthday Bash at Belly Up February 17

Steve Poltz is probably best known for his stint with the Rugburns, of “Hitchhiker Joe” fame, and for recording two albums with Glenn Tilbrook of Squeeze. His Taylor 510, manufactured locally, has its own claim to fame as the guitar he used to write “You Were Meant For Me,” which became a hit for fellow local Jewel. Poltz will celebrate his 50th birthday for the 15th time by welcoming a guest player Jay Cobb Anderson of the band Fruition to the Solana Beach stage.
