“I can do this” should be the working mantra for Hawaii-born singer-songwriter Sabrina Velazquez.

Thanks to the inspiration of a former guitar-playing skater boyfriend from her college days, Velazquez has blossomed into an emerging indie rocker in her own right. Her self-released EP, “The Anomaly,” has garnered her some buzz on the Internet since it came out in February, and Velazquez hopes to build on that locally with a solo showcase at Hank’s Cafe downtown tomorrow. (She’s also the featured artist June 20 on KTUH’s “Songwriters Showcase” program; visit www.ktuh.org for more.)

Now in “the twilight of her 20s” (said with a humorous, pseudo-dramatic flourish), her musical journey has come a long way from wanting to impress a former beau when she was attending the University of Southern California. It was that can-do attitude that had her first learn “Knockin’ on Heaven’s Door” on “a cheap Epiphone guitar,” to taking classes in pop-rock and jazz guitar while at USC.

“I found learning music to be really challenging, like solving a puzzle,” she said.
