Henry "Pucho" Brown and the Latin Soul Brothers put out a string of influential records in the mid-'60s, fusing Latin jazz, soul and funk, and for a while were all the rage.

Friday at the Birchmere (703/549-7500), and Saturday at the Ram's Head (410/268-4545), it's NRBQ, a band that for 30 years has put together a body of work (rock/pop/jazz/country/novelty) that would make any other band envious (NRBQ will also be taping a segment for the PRI radio show "Mountain Stage" Sunday night at the Apollo Theater in Martinsburg, W.Va., if you're up for a road trip. Also on that taping will be Fred Eaglesmith and Scooter Scudieri [800/498-2386]).
