Sponge was one of the more underrated groups in the post-grunge boom of the mid-'90s. When they were on top of their game -- as evidenced by the hits "Plowed" and "Molly (Sixteen Candles)" -- the band's songs had a knack for jangly riffs and catchy, anthemic rock hooks, despite being wrapped in the fuzzy guitars and brooding seriousness that typified grunge music. Sponge grew out of a Detroit-based rock act called Loudhouse, which released an album on the Virgin label in 1988 before losing its record contract and disbanding shortly thereafter. Drummer-turned-vocalist Vinnie Dombrowski (born Mark Dombrowski) and guitarists Mike Cross and Joey Mazzola regrouped as Sponge in 1992, adding Mike's brother Tim Cross on bass and Jimmy Paluzzi on drums. Adapting their '70s rock influences to fit the grunge zeitgeist, the bandmates earned a major-label deal with Columbia and released their debut album, Rotting Pinata, in late 1994.

Initially, critics compared Sponge unfavorably to Stone Temple Pilots, but alternative radio embraced the band's first two singles: the driving rocker "Plowed" and the jangly, introspective "Molly (Sixteen Candles)." A third single, "Rainin'," also earned airplay, and Rotting Pinata went gold; meanwhile, Sponge went on tour as Live's opening act. With new drummer Charlie Grover in tow, their 1996 follow-up album, Wax Ecstatic, was a more diverse affair, rediscovering some of the band's roots in rock, British glam rock, and jangle pop. Even though singles like "Wax Ecstatic (To Sell Angelina)," "I Am Anastasia," and "Have You Seen Mary" enjoyed some degree of radio airplay, Columbia was dissatisfied with the sales figures and dropped Sponge once the album left the charts.

Undaunted, Sponge signed a new deal with the Beyond label, which released the more classicist "New Pop Sunday" in 1999. It attracted little commercial attention, and more personnel shifts ensued. Tired of touring, the Cross brothers both left and were replaced by guitarist Kurt Marschke and bassist Tim Krukowski; Billy Adams also came on board as the new drummer. After several years of recharging -- during which time Dombrowski played in several Detroit-area side projects -- Sponge returned with Sponge-For All the Drugs in the World in 2003 and American IV: The Man Comes Around in 2005. Dombrowski reworked the lineup once again, this time adding guitarists Kyle Neely and Andy Patalan, before returning again to the studio in 2007 to record Galore for Bellum Records. ~ Steve Huey, Rovi
