As if musicians needed another reason not to make it into work. The Tantrums Jam, hosted each Wednesday night at Kokopelli's by Tempa Singer and her Tantrums bandmates, has become the mid-week gathering place for local players to get loaded and get down. While guitarists currently make up a majority of the jammers, a fair share of drummers, bassists and singers also make it out for the impromptu performances. So whether you're itchin' to unleash your pipes on jump-blues cuts like "Caldonia" or jonesin' to shred on tunes like "The Sky Is Crying," there's bound to be someone who's willing to throw down. And if that weren't enough to entice you, catching an eyeful (and earful) of the fiery Singer should seal the deal. The stunning homegrown diva has shared the stage with legends like B.B. King and Jeff Beck -- and she might share it with you, if you've got the chops.
