One of the finest musicians to ever call San Diego home, guitarist Peter Sprague has long been a certified jazz legend. Prolific to a fault, he performs alongside vocalist Dianne Reeves, fronts such groups as Pass The Drum and The Peter Sprague String Consort, and has a discography that numbers into the dozens of titles. On Nov. 20, Sprague takes a look back at his early days when he reunites with his late ’70s era group Dance of the Universe for a one-off performance at Tango Del Rey. As incredible as a typical Sprague set can be, this reunion of old musical friends should spark some real onstage magic. Peter Sprague and Dance of the Universe: Friday, Nov. 20, 7:30 p.m., Tango Del Rey, 3567 Del Rey St. $10 students,. $15 general. All ages. It didn’t take long for Al Howard to follow up his revered soul and funk based K23 Orchestra, which folded in December of 2008. Now the man behind the Heavy Guilt will appear at RT’s Longboard on Nov. 24. Howard’s music has shifted to a mix of folk, psychedelic and indie rock, with hints of Traffic, Cream, Wilco and Elliott Smith. Though the Heavy Guilt doesn’t have the same rhythmic attack of his previous group, their songs are no less intense. Longtime fans of Howard’s music will love his latest incarnation automatically, but any fan of classic rock or folk based modern indie will want to check this band out. The Heavy Guilt: Tuesday, Nov. 24, 11 p.m., RT’s Longboard, 1466 Garnet Ave. 21 and up. Although the evenings are beginning to get a little chilly, you can get back a little of the feel of summer at the beach Nov. 25 when reggae group Roots Covenant performs at PB Bar & Grill. The heavily dub influenced South Bay band released an eponymous album in 2007, building up a sizable following in the ensuing time through relentless gigging. The hard work shows. If you’ve become jaded by the over proliferation of reggae groups in the past few years, give Roots Covenant a listen. Their tunes avoid genre clichés and prove their members to be particularly adept with a melody. Roots Covenant: Wednesday, Nov. 25, 6 p.m., PB Bar & Grill, 860 Garnet Ave. 21 and up. No Cover.
