Rick Parashar, the owner of Seattle's London Bridge Studio who helped shape the '90s alternative sound by working on seminal records by such bands as Pearl Jam and Alice in Chains, has died on Aug. 14 at the age of 50.

According to Northwest Music Scene, Parashar suffered a pulmonary embolism when a blood clot in his leg moved up into his lung, restricting the blood flow from his heart. Parashar died at his home in Seattle's Queen Anne neighborhood.

With his brother Raj, Rick Parashar built London Bridge in 1985. Over the next few years, many bands from the nascent Seattle scene began to coalesce around the studio. Three of the defining albums of the grunge era -- Temple of the Dog's self-titled album, Pearl Jam's 'Ten' and Alice in Chains' 'Sap' -- were produced by Parashar.

In later years, he worked on such commercially successful records as 3 Doors Down's 'Away from the Sun,' Nickelback's 'Silverside Up' and Bon Jovi's 'Have a Nice Day.'
