Bob Mould has always been a musical chameleon, and his latest endeavors are no exception. With all that he has accomplished in the past decade, it’s hard to know which side of Mould will be seen when he performs at the Maintenance Shop Monday.

As a founding member of the early ’80s rock group Hsker D, Mould shaped the future of alternative music long before anyone had even heard the name Kurt Cobain. With a sound that was equal parts punk and indie rock, Hsker D proved that a band could sign to a major label and still stick to its independent roots.

After the breakup of Hsker D in 1987, Mould signed a contract with Virgin Records as a solo artist. His first solo album, “Workbook,” gave Mould the chance to give a more introspective, softer sound to his music, and was met with a great deal of critical acclaim. The album only made it to No. 127 on the charts, but the single “See A Little Light” became a Top 10 hit on modern rock radio.

Upon releasing his second solo album, “Black Sheets Of Rain,” Mould left Virgin due to creative differences. This gave Mould the opportunity to leave his introspective solo image behind. His next band, Sugar, returned to the grittier independent sound of Hsker D, and ended up becoming Mould’s most commercially successful project to date. Sugar’s debut album, “Copper Blue,” almost went gold, and managed to get airplay on MTV for the singles “Helpless” and “If I Can’t Change Your Mind.”

When Sugar came to an end in 1995, Mould once again returned to his solo work, this time on his own label, Granary Music. This year, Mould released three albums almost simultaneously, each with a completely different musical style. “LiveDog98” continues with the simple rock sound of his previous albums, but “Modulate” delves into a completely unexplored genre for Mould — techno. His third album, “Long Playing Grooves,” which was released under the band name LoudBomb, showcases Mould as a DJ. Mould’s new musical direction proves once again that there is no musical style that he can’t conquer.

Mould’s album catalog is long enough to keep one’s ears busy for months, but here is a sampling.

Hsker D:

“Everything Falls Apart” (Reflex) 1982: The band’s first studio release wasn’t groundbreaking, but it did set the stage for Hsker D to become a major influence in independent music.

“Zen Arcade” (SST) 1984: Allowing an indie punk band with identity issues to release a concept album could have been a bad idea, but Mould and guitarist Grant Hart managed to do it with style. This album became a major influence for similar independent bands during the mid-80s.

“Flip Your Wig” (SST) 1985: With the assistance of a new producer, Hsker D gave a cleaner, more melodic approach to its brand of post-hardcore rock. Through blistering guitar techniques and poignant vocals, “Flip Your Wig” became the quintessential Hsker D album.

Sugar:

“Copper Blue” (Rykodisc) 1992: This album is Mould’s most commercially successful album to date, with several singles reaching MTV and radio stardom. With a sound situated firmly between Hsker D and his solo work, Mould created an album that appeased both fans and critics.

“File Under: Easy Listening” (Rykodisc) 1994: After an unsuccessful recording session in 1993, Mould completely erased the first version of this album. He decided to give it one last try, and the result was a solid rock album that couldn’t quite match the commercial success of its predecessor.

Bob Mould:

“Workbook” (Virgin) 1989: After the fall of Hsker D, Mould set out to create a softer sound for himself. Workbook was his first effort, and a groundbreaking one at that. Raging guitar riffs were replaced with cellos and acoustics in a style that has become distinctly his own.

“Modulate” (Granary Music) 2002: The mixture of rock and techno may be completely unique, but it takes a few listens to really understand where Mould is taking the future of his music. Whether you agree with the new sound or not, it is clear that Mould has accomplished his goal of separating himself from his old sound and his past.
