For Mark Winters, the distance between a scientific equation and an emotional connection may be smaller than it appears. The Texas-based singer-songwriter and bona fide rocket scientist has built a musical identity around an unusual but compelling combination of analytical thinking, poetic expression and unashamed optimism. His signature sound, “rock with a positive vibe,” reflects a belief that music can illuminate everyday experience, encourage personal growth and bring people together without sacrificing the energy and spontaneity of rock ’n’ roll.
