RICK ESTRIN & THE NIGHTCATS, SUN AND MOON CAFE, Monday, Nov. 26 and Tuesday, Nov. 27, 7 p.m., $25

For more than 3o years, singer/harmonica man and songwriter Rick Estrin was the frontman for Little Charlie & the Nightcats, a San Francisco-based blues crew whose sound was defined by the combination of Estrin's rapid-fire harp and comically dashing persona and Charlie Baty's guitar. When Baty retired, Estrin kept the rock-solid rhythm section in place and found a new guitar man in Kid Anderson. The quartet just released their sophomore album, One Wrong Turn, and it's a winner beginning to end, delving into a variety of American rock and blues styles on strong original songs and well-chosen covers. Combine a veteran band like this with the kicked-back atmosphere of the Sun and Moon Cafe, and throw in some of the tasty grub from the cafe's kitchen, and you have some serious early week options on your hands.
