The Office (9 p.m., NBC) is back tonight for its fifth(!) season. Like last season, the series will begin this season with four one-hour episodes. Tonight's tale explains what happened over the summer at Dunder-Mifflin in four 15-minute increments. Did Jim propose to Pam? Did Andy discover Dwight's tryst with Angela? Did Michael sort-of become a dad? Did hilarity ensue? Find out tonight. Also, EW posted a run down of Season 4's best and worst moments, and Watch With Kristin has a video interview with Amy Ryan, who joined the cast as HR rep Holly Flax in last season's finale.

Also back on TV's biggest night are Ugly Betty (8 p.m., ABC), My Name is Earl (8 p.m., NBC), Survivor (8 p.m., CBS), Grey's Anatomy (9 p.m., ABC) and ER (10 p.m., NBC). And don't forget the hour-long block of It's Always Sunny in Philadelphia (10 p.m., FX).

There are many great concerts going on tonight too. Tops is probably Gentleman Auction House at High Five, 1225 N. High St. I wrote about what makes this epic pop group from St. Louis so good, but the rest of the lineup, which includes Chicago's Big Kid Static plus locals Bookmobile and The Thrashers makes for enough solid support to make this one of the top shows of the week. 10 p.m. start, $5 cover.

And what about the happening tonight at The Summit, 2210 Summit St.? Detroit's shitgaze kings Tyvek will be in town for a show with Guinea Worms and The Lindsay. 10 p.m. start, $5 cover for this too.

Also, the lineup at The Basement, 391 Neil Ave., ain't nothin' to sniff at either. Roots rock balladeers Backyard Tire Fire and drawling indie rockers Ha Ha Tonka, two regular visitors to these parts, return to join forces with fast-rising local twee representatives Our Cat Philip. Doors open at 7:30 for this one, with tickets $10 at the door.

There aren't many nights when I would recommend four different shows, but fall concert season is in full swing. Our fourth selection comes courtesy of Blastronauts's James Allison, whose Outer Sounds concert series kicks off tonight at Bernie's, 1896 N. High St. Cincinnati's The Seedy Seeds and Dayton's New Vega are in from out of town, but it's local weird-pop acts Couch Forts and Flotation Walls that have my interest piqued. I would assume this also starts at 10 and costs somewhere in the range of $5.
