If the thought of a brass band has you picturing parks and parades, it may be time to reappraise with help from the Youngblood Brass Band. Hailing from all over the US, the nine-member horn-and-percussion group has been busy rewriting John Philip Sousa's rulebook — the YBB even got Talib Kweli to pimp out their big-band sound on their 2000 debut album, Unlearn. Several world tours later, Youngblood treat Europe to more sometimes-booming, sometimes-political, sometimes-mellow, crunk-influenced riot jazz.
