Nonprofit record label and even production company JDub Records will celebrate its five-year anniversary with free concerts this summer in New York, Denver, Cleveland and Los Angeles.

The first free show will be held July 20 at Celebrate Brooklyn in Prospect Park, with performances by JDub acts Golem, Soulico, Deleon and Sway Machinery. Comedian Michael Showalter, who last year released stand-up album "Sandwiches & Cats" via JDub, will host the Brooklyn concert.

Additional free concerts with various JDub artists will be held at Denver's Walnut Room (July 23), Cleveland's Grog Shop (July 24) and Los Angeles' Grand Performances (July 27). The shows are free, but JDub is suggesting that concertgoers donate $3. Several organizations have been enlisted to sponsor each event.

Since launching, JDub Records has worked to develop and promote Jewish artists. The company was responsible for introducing Hasidic reggae rapper Matisyahu, who left the management company in 2006 to sign a new deal with former Capitol Records president Gary Gersh. Along with a handful of concert appearances this summer, Matisyahu is working on the follow-up album to 2006's "Youth."
